The sequel - LASERS: ua-cam.com/video/ZH3yMeA7HxQ/v-deo.html We measured at 2m (not 1m) because thats what the horn specs sheets say! The bomb correction should say 10,000X the Nagasaki FatMan explosion. Bonkers. Also the % greater than Hella can be simplified and corrected as (from top to bottom): 1.15X, 1.19X, 1.72X, 2.29X, 2.57X & 1.46X
I've had good results with two different horns on my cars. Both made by Stebel, one is an air horn called nautilus and one is a twin electromagnetic pair called Magnum. Both claim high noise the nautilus 127db and the Magnum pair claims 115db. To my ears they are a similar noise level but the nautilus is a high tone air horn type like a stadium horn and the Magnum is a more aggressive "GET OUT THE WAY" type.
@Eric Duckman You know you can just buy some reputable Chinese cells from reputable sites like 18650batterystore, instead of off eBay right? And besides, Project Farm already tested this. Or are you trying to say they should test how close the actual capacities are to the advertised ones of the reputable 18650s?
I noticed this same thing on wish a couple years ago. Something like 7-8000 decibel horn for your truck. I did a lot of research and concluded that obliteration of every atom in the universe would only cost about $30(S&H not included) 😂 Glad someone turned this into a video, you killed it
I love that we got a history and geology lesson for a joke. We even got math and science lessons in this video. I appreciate the effort and dedication for a bunch of cheap Amazon horns.
The biggest joke was the fact that someone trying to explain something scientific, could not even get the basic math right. 200 Mt is not 20 Kt x 100. 200 Mt is 20 Kt x 10000.
fun fact: emergency vehicle sirens has a range of 110-129 db, 120 db will cause permanent hearing loss at 2 meters if exposed for more then 30-45 seconds and temporary damage if exposed for around 5-30 seconds, this is why emergency vehicles turn off their sirens if they get stuck in traffic and when they pass through tunnels, if they did not they would cause thousands of cases of temporary and permanent hearing damage.
They also turn them off when stuck in traffic to avoid pressuring drivers into panicking and making mistakes that would cause an exponential increase in the number of emergency vehicles needed.
I can only imagine what your neighbors thought when all of them went off at once. Sounded like a comically large crash involving several jingle trucks lol.
An interesting test for sure, but as their tones are not always constructive, interference will usually act to reduce their amplitude. If he had hooked multiple of the same horn up and tested that, there would have been a much greater chance to increase the amplitude. As this is the Torque Test Channel and not a The Who concert, I didn’t anticipate that kind of test. Was still happy to witness it (via VOD), and also happy I was not present even at distance in the industrial park they were testing it in.
Glad someone finally said this. I've been leaving the following reviews on several Amazon horns: 109db - chainsaw operation 130db - painful to most humans 150db - can break human eardrums 172db - Krakatoa explosion at 100 miles away 175db - one ton of TNT at 250ft 194db - limit of what we can scientifically call "sound" before it just becomes a pressure wave. ... 300db - these horns apparently
@@ExtraThicccOh God, you said it. When Amazon sellers go out of their way to sell product equivalents to teddy bears full of glass shards, and then abuse the system's lax policing to try and create their own echo chambers while flipping customers off in the process, I WILL fucking let them know how I feel. Amazon would never allow people to do that, let alone let the sellers moderate their own customer reviews. It doesn't matter if you're a small business owner, if you're a multinational corporation. If you're big, small, if you're a team of 600 or a solo-man job. If you put shit on the internet and want to charge people money for it, you're officially making a product, and you WILL be criticized as such.
The reason 194 dB is the limit in 1 atmosphere is because of the wave troughs/rarefactions clipping into vacuum. So the full wave can no longer form, due to there being no lower pressure than a full vacuum and the opper pressures having to work with 1 atmosphere of air. Though in reality and with real air an its thermodynamic properties the waves start distorting non-linearily from around 150 dB already. To get beyond those 194 dB you need extra air-pressure from somewhere. And that somewhere in practical terms is generally an explosion producing a whole lot of localized extra gas volume.
I love that based on the seller's descriptions you're actually testing doomsday weapons. "According to the seller this should wipe out my entire city for 28 dollars, let's test it out."
Great video! Kinda bummed that none of these horns ended all life on earth, reversed time, and opened a wormhole to an alternate reality, but it was fun all the same.
But I guess the major philosophical question your statement creates is this: if one of these horns had ended all life on earth, how would anyone or anything know if time was reversed or not? 🙂
I will say the little remote pumps for these horns are a huge limiting factor. I had one I was playing around with and hooked it to 130psi shop air. I was not ready
I just love the one time in Teen Titans comics when Cyborg used a million decibells of white noise at the enemy. That is like 10^100000 universes of energy lmao.
I'm pretty sure it's based on energy/pressure waves over distance rather than how loud we actually perceive it, which is why there's no simple "is it loud" scale. We all perceive sound differently.
@@cherrypepsi2815the logarithmic pattern is like that because it is intuitive to the way our ears work. something that sounds twice as loud to us is many times as powerful. its confusing to liars selling bootleg products to ignorant fools, but anyone that looks it up and tries to understand it is pretty good.
Fun fact, the largest supernovas are estimated to be about 450 decibels. I have a feeling something at 600 decibels would be so much energy density that it would likely create a black hole.
Yes, if these things were actually 600db. They'd pretty much be super weapons, and would kill the owner and probably take out an entire city, and probably the world. 1100db would probably cause a black hole. Thankfully Amazon doesn't sell super weapons for under 100 dollars, that can cause shock waves that would destroy cities in an instance.
This was UNREASONABLY funny and entertaining for what it was. My wife is not a technical person, would have never clicked on this video, and was dying of laughter just overhearing the video. Well done. 10/10
Thank you for mentioning that decibels are logarithmic, seeing the numbers claimed made me laugh. Seriously, those things would probably create a pressure wave big enough to destroy the planet at the advertised volumes
600 dB is probably the sound of the entire Earth exploding, whatever "sound" means in that particular scenario. EDIT: More like galactic explosion, thanks to those who did the math.
Ok, let me see: If we use a speaker rated at an amazing 100 dB at 1W/1m , to get 600 dB SPL, we'll need... wait... 100 + 10*log10(x) = 600? Solve for x... 10^50 watts!! Our sun only releases on the order of 10^26 watts. Even better, the energy contained in a supernova is "only" 10^44 joules! Consuming an entire supernova couldn't power those speakers for more than a microsecond.
I love the whole one minute and thirty-five second explanation of the loudest recorded sound known to man, then the five second chat of the cheap amazon horn claiming to be twice that and you going "God help us all" XD Love the video and the testing. Thanks!
Not twice as loud, actually; the decibel scale is logarithmic. 600 db is 1*10^29 times louder. So multiply the volume of the eruption shockwave, by the number of people on the earth, and then by the number of stars in the entire universe, and you'll be pretty close to how many times louder 600db is than 310db.
@@2005cms You have one billion, 1,000,000,000, and then imagine you have a trillion, 1,000,000,000,000, of each of those billions. That's "a trillion billions." Good luck imagining that 🤣 quite literally universe ending. Maybe there's some ridiculous calculator on the internet that can illustrate it for you, but it'd probably be reported as spam if someone showed you in a UA-cam comment from the sheer amount of zeroes
That prologue of describing the largest recorded volcanic explosion and then the "it was 300 dcb, this horn is rated for 600, god help us all" LMAO , i fuggen lost it.
There's two decibel scales! Your calculator at 4:13 uses a scale of 20 decibels = 10x, and your calculator at 5:36 uses a scale of 10 decibels = 10x -- this is why the second calculator shows about half as much increase as the actual measured amount. (109 is right between 106 and 112!) Your device definitinely measures on a 20db scale according to its results.
As the foremost expert in Birdlaw, I can tell you that you have a case. And once Vovov accepted your $22 they are legally and contractually obligated to provide you with a horn capable of destroying the earth. That obligation doesn't end with Vovov either; If they do not have the resources then the entirety of China also has no other option but to fulfill the legal obligations of Vovov, under international Bird law. Trust me, I know this, as I studied under the Big Bird himself.
You should have ran compressed air through the horns and ramped it up incrementally with a regulator until they blew. Just to see what the max capable loudness was.
@Gol Acheron Start at around 15psi, Keep going until around 150psi(that's about the limit of most common compressors. But I've s feeling the horns will probably give out at around half that.
@@atourdeforce we ran shop air through some cheap air horns where I used to work. About 120psi. Don't know about long term use, but none broke from us just fucking around with them
Your rating system, content ideas and humour are honestly second to none. You, AvE and Project Farm are keeping us do it yourself guys goin. Please don't ever stop. 💯👍
I think there may be something wrong with the Vovov unit you got. I installed one in my car and on the first honk it leveled the tri-state area. 10/10, would recommend.
I commend you on your bravery for the risk that you took testing these horns. If their advertising was indeed genuine, we would all be extinct right now, but that didn't stop you from testing them anyway. Respect
My wife asked “something amusing?”, as I was laughing in bed. She had previously glanced over and assumed I was watching a boring documentary on Krakatoa. “Check out this set up!” I replied with tears in my eyes. Great stuff.
Something important about traditional automotive “horns” (not the air horns) is that they need to be rigidly mounted to something in order to get their best noise. That’s why some of these sounded so weak. Just sitting them loose on a surface means they lose some of their power. Regarding the stupid/not based on reality ratings on Amazon, these no-name companies are capitalizing on the ignorance (i.e. stupidity) of the average person and the general mentality of “more is better.” It doesn’t have to be based on reality, as long as it is more “rating” than the competition (and unbelievably cheap), people will buy it.
Regarding mounting, the infamous "beep-beep" Roadrunner car horn from the late 60s and 70s achieved it's unique sound partially through the mounting bracket design. Unmounted they have an entirely different sound
I don't think it's "stupid" of anyone to think that 300db is 150db x2. It really is just ignorance of the scale that is counter-intuitive to all other everyday units of measurement. It's the same with batteries. Consumers are expected to weed through a legitimate shopping website filled with illegitimate entries, and people of average knowledge/patience/trustfulness can't be expected to always know that there aren't really 6,000mAH 18650 batteries for consumer use. It's straight up scamming people who haven't been given the tools to know better, especially because any research on the subject on a google search is flooded with "TOP 10 18650 BATTERIES" with affiliated amazon links.
@@whompronnie just use a better ad blocker. A new product from the arrested development Corp DBA Faceblock prevents 210% of all identity theft. And I expect competitors to emerge soon with ad blockers that remove 300%. Eventually removal rates of 10s of thousands may be possible. The only limit is our imagination since these are not real numbers anyway. Eg "New gluten free recipe! We removed 200% of the gluten. (Means our product has negative gluten so you have eat gluten from somewhere else to get to zero)"
Fun fact, they estimated the pressure output from 2 black holes colliding several billion lightyears away was around 1100db. Which is enough pressure that it shook the fabric of reality it's self. That's how it was recorded.
Time stamps for the various horns actually blowing, in case you want to *compare tones* quickly: 3:42 Hella 5:07 and 5:20 ZBrand (second lowest price; medium, dual tones ) 7:15 TWOM 8:34 Viking Horns 9:50 Yaetek (lowest price; low-ish pitch, single tone) 10:46 Mega Blast 12:22 Vovov (third lowest price; high pitch, almost squeaky upper tone) 12:48 for the final comparison chart I would be very interested in hearing pairs of these horns, particularly the Yaetek single and the ZBrand twin blowing at the same time. How do the loudness factors combine for 3 tones at once? Love this video. @Torque Test Channel
@@tjf9948 fortunately it's rather easy to rent very large trailer mounted air compressors designed to be used by large construction crews running multiple high airflow tools, to that equipment blasting three or four very large air horns continuously would be a walk in the park.
I do appreciate how you (TTC) use the things you demonstrate as a jumping-off point to teach about other things like a bit of history or basic metallurgy.
I have to say that the first 2 and a half minutes of this video have to be the best video introduction I've ever seen on this platform. Hats off to you
A good reason why you wouldn't get as much sound as you think you would running all those horns at once is that the mix of all those frequencies would generate random standing waves that would effectively mute or "cancel out" some of the sound.
You could really expand your content if you wanted, testing historical claims against modern standards. At any rate, delivery of information was entertaining as always.
Didn’t mean to change the format of TTC, we’re all here because we enjoy the channel. But the rhythm of his narrating shouldn’t be overlooked. He’s a natural lol
OMG thanks so much for this! I bought and hooked up that Vovov a few weeks ago but had been afraid to use it incase the pressure wave vaporised the planet, extinguished the Sun, perhaps even sent the Milky Way cartwheeling into Andromeda. Turns out it's just a slightly grating parp. You've put my mind at rest. 🤗
I'd like to see LED Spots and bars next, another one of those things you can never tell how good they really are unless you have the test equipment. Keep up the great content!
That was fun !! I have a Toyota Tacoma, and the horn is embarrassing, so I'm going to the junk yard and get a dual horn set off of a Cadillac. I had a 49 Cadillac Fastback, 6 volt dc. I restored it and upgraded the electrical system to 12 vdc. That single horn on 12vdc. Was so loud it ring my ears every time I tooted it, not only was it extremely loud, it also fried every horn relay I bought. Finally I bought a 12vdc. Ford starter solenoid, and wired it up, then it worked GREAT, I measured the current draw on 12vdc. It was almost 80 amps.!! It really was extremely loud !! Louder than a real truck airhorn.
@@Corrodias I just got a pickup and someone about hit me in traffic. They were completely not phased by it and I learned the horn is less alarming than the one on my focus
Thanks. I'm shopping for a horn to replace the anemic OEM horn on my car, and you saved me from doing the same test you did. As I recall Hella made a 3-trumpet air horn decades ago that was obnoxiously loud.
A pair of OEM style trumpet horns will probably be just fine, they're plenty loud to be heard above most things. Whatever you do, don't remove your stock horn because if you ever get pulled over for it if you're in the US it could land you with an expensive ticket
@@Channel-gz9hm "Non working horn" is different from "illegally installed air horn." One will get you a fix it ticket, the other is more likely to get you permanent citation. Non working equipment is one thing, and you're right, it would just be a small fee if you didn't get it fixed. But non-working and "modified in a way that violates the regulations pertaining to motor vehicle equipment" are two different things.
@@Channel-gz9hm Almost every state, save for Maine, South Carolina, and Vermont have laws stating some variation of "no horn may emit excessive noise," which is indeed a somewhat vague law, but some states more specifically target air powered horns, sirens, whistles, etc. Some states also have a law that states that air powered horns are legal as a _secondary_ warning system (i.e. not hooked up to the horn button on your steering wheel) IF the vehicle is equipped with air brakes and the horn is plumbed in to only pull pressure from the air brake tank. There are no states to my knowledge that explicitly state that air horns may be hooked up as a primary warning system, meaning they are hooked up to your steering wheel and replace the stock horn
@@richardmillhousenixon General rule of thumb is no louder than 100-110 dB. Personally, while the stock OEM electric horns on my truck are plenty loud for me, I've kinda wanted something a bit more like whatever the sound crew did for the War Rig from the last Mad Max movie...
Admittedly we were a bit out of our depth to know which were the "legit" ones, but for the most part we avoided the "needing you own air tank and compressor" bunch of horns as that category seemed to pray on the ignorant consumer less than this type. If you have an air tank already you're probably not buying $20 600dB horns we felt :P
@@FOXCRF450RIDER I've always felt like those are just antisocial. They're so incredibly loud that nearby pedestrians can suffer permanent hearing damage in a matter of seconds. For me that was part of the reason why I upgraded my moped horn from a 96dB single to twin 117dB horns. The sound is more directional and they're on the egde of being so loud it hurts your ears. Sadly with most school going teenagers on their bicycles wearing earpods these days, 96dB just doesn't cut it any more. You need to be louder than that or they just straight up won't hear you. Also the 117dB horns were the loudest I could find that worked on 12V AC and had an E-number. I wouldn't want some overzealous cop to suspend my registration because of a horn.
@@TorqueTestChannel I have some old foundry cast air train/truck horns that were cast and made in Los Angeles the foundry doesn’t exist anymore so there pretty cool be happy to send them to you guys to test against the rest of them.
Funnily enough, this isn't false advertising. They don't actually claim it's 600 dB, it says 600DB, which could be their model name. Misleading but not outright false advertising. And yes, this is why lawyers go to hell.
Usually I get irritated when people try to explain decibels as a pressure wave and perceived intensity, but you did a great job. You definitely understand your math.
@@sperzieb00n You are correct. His math may be wrong, but the understanding is mostly accurate. I've seen so many other youtubers claim "A 3dB increase is twice as loud" which falsely confuses electrical waveform power with pressure wave perceived loudness.
at 600dB it wouldn't just move someone out of the way with the shockwave. It would release about 1x10^48 Joules of energy. To say that's a lot of energy would be a significant understatement. It would literally vapourise the solar system into a rapidly expanding plasma (everything, the sun would be blown away by the energy release like you blow flour off a kitchen countertop), it's entirely like a few neighbouring systems would go that way too. Your "horn", over time, would be easily detectable across the entire visible universe with current technology. Of course in actuality putting that much energy into such a small item would like mean that it would collapse into a medium sized black hole. Regardless, someone being in your way wouldn't be biggest problem anymore 😂.
You will probably find the Hella horn will increase a couple db once it is bolted to a sufficient part of the vehicle & the tone will usually change also. Should have got a truck horn & used a air compressor to see how much louder it is or even with the cheap car horns they usually get a lot louder.
I'd have liked to see a Cadillac 4-note horn set tested, since those are by far the loudest (and best sounding) OEM horns I know of. I've pulled a few sets off junkyard cars to put on mine.
Heck yeah! Those 4 note GM horns are classic and legendary! (Especially if you grew up in the 60's and 70's!) One of my favorite GM commercials is the one where they take a Tahoe with the same horn, and put it on a revolving platter to become the "new" lighthouse! It totally works and trips you out because they slowly zoom in from a very far and wide angle perspective on a dark foggy scene. You just hear the fog horn and see light sweep by. It's not until they get close enough you realize it's a Tahoe rotating on top of the light house with it's high beams on sounding the horn. I'm sure it's not real, but it still messes with your brain. It was probably just marketed to select regions like mine (New England), perhaps the Great Lakes and the Pacific NW. No one else would get the reference or have that lighthouse sound embedded into memory like we do growing up with it! LOL
In the motorcycle world, the Denali Soundbomb series is really popular, if you do another one of these tests I'd recommend including either their original or split. I've got their split and it is VERY loud compared to a standard motorcycle horn
Oh boy, not only do I get blinded by SUV headlights on low beams by driving a sedan but if this catches on, I can be deafened as well. I wonder what new pleasures await on the road.
@@FOXCRF450RIDER For sure, but I now think it's SUVs and pickups which are so high that the darn low beam is in your eyes when you drive a normal car. It's horrible and it's dangerous.
They rely on people not knowing and understanding log scale measurements. I am a retired test engineer and I have no complaints with your test method. I was in the market for a good horn and the aftermarket claims for dB just left me to keep my stock horns as I knew they were BS. I guess I will eventually get a Kahlenberg KM 165 ship horn with a REAL 143 dB. At 34x18x18 in. it should fit in the back of my RAM Express.
A lot of the trumpets themselves have a diaphragm which'll start to rust and cause air leakage, reducing the volume of the horn. I thought my (long gone) airhorns had an issue with the pump, because it'd just whirr away when energised, so after getting an identical set, I replaced the pump. Same dealy! Swapped back everything, so new trumpets with old pump, loud as I got the originals on day 1. Best I could do to prolong them is to drip oil into the hole where the hose goes, and onto the diaphragm through the sound opening. Then give 'em a few blasts to let the oil squish around and get into the contact area between diaphragm and trumpet. The pumps also wear around the seals, so cleaning the innards and reoiling should be general maintenance on those beasties, too, even though no one ever brings it up.
I need to start making horns and put up a graph against actual explosions to truly scare people in my marketing materials. "Buy our $18 horn and literally blast the cars around you off the planet"!
IIRC the default distance for sound measurement is 1m Edit: And don't forget - an increase in 3dB does *not* make it double as load. Yes, the effect needed to increase 3dB is 100%, but for sound to be audiable double the strength, you'll need to increase it by 10dB. Interestingly, 3dB is also the limit to which the average person can register a difference (lower or higher). People working with music and similar, can often differ between lower changes than 3dB, but those are mostly exceptons.
The two dual horns likely exhibit what is called constructive interferance, which means their sound waves merge together and make a larger one, making it louder than just the sum of the two horns, or at least my guess
I think constructive interferance can only cause twice the original waveform at max because when waveforms exactly match in amplitude and inverted phase, you get the maximum and that's only double the original. If the summed waveforms have different frequencies, the resulting oscillation in the sound may be something that the dB meter reacts to but I'm not sure why. The video didn't mention if the meter used A, B, C or Z weighting. I think the dB calculator on the computer probably matches only the Z weighted meter (which is the only one that actually meters the energy in sound, other more or less try to measure human hearing instead).
i suspect theanufacturer might have made the 2 horns have different pitches on purpose, as having 2 horns with matching pitches would potentially risk destructive interference if for some random reason, one horn starts off with inverted phase.
@@kirkhamandy Yes, if the soundwaves interfere destructively that would result in silence. However, executing this in practice with two sound sources in two different physical locations (e.g. 5 cm away from each other) causes the silence to project "between" the sound sources and lobes of sound diagonal from the projected silence will see constructive interference and double energy (imagine waves in water from two separate objects but in 3D in air).
@@kirkhamandy Yeah, I figured it out from "Schrödinger's Horn" part but the destructive interference was still a good point which is why I added a real comment about it.
5:35, that calculator assumes sharing same power. 2 horns getting individual power should get +6dB, and they did. Same for speakers. Daisy chain 2 speakers and you get +3dB, give them each power and you get +6dB.
Heh, reminds me of working in a powersports dealership. Customer wants a 10,000 lb winch. "Sir, your vehicle only weight 500 pounds." Nope, I gotta have the power to snap my frame in half or I'm not happy lol.
Always remember kids, decibels are logarithmic, meaning a +6 increase in decibels is twice as loud, +20 is 10x, so a 600 decibel horn would be about 10^25 or about 10,000,000,000,000,000,000,000,000 louder than a 100 decibel concert
I went through the waters by Krakatoa While sailing aboard the USS Enterprise CVN 65 and it was one of the most Eerie places I've ever seen in my life.
I bought some expensive air horns (a set of 3) awhile back and installed them on my truck. They were rated at 140 dB at 120 PSI and they were loud! If you were standing next to my truck even a short blast would cause you to cover your ears and you could actually feel the concrete vibrate! So you can buy very loud air horns but they cost more than $25 and in my case I had to supply my own compressed air.
A big problem with Amazon is sellers can suggest changes to an items listing. And other sellers will suggest changes that are completely wrong every time.
thank you for fixing the sounds to make them easier to listen to, it surprises me how few youtubers edit the audio on their videos in 2022 but im glad to see some people are still doing it 😆😆
I appreciate the audio adjustment, but I really love the use of an actual decibel meter and standardized testing. It's really subjective whenever anyone reviews a horn, exhaust, etc. on the internet. You're often relying not only on the varying quality of the recording equipment, but on the individual viewer's playback equipment and even their personal hearing quality and opinions.
@@rebturtle I agree, a decibel meter is much more accurate than a persons ear, especially with all the damage a persons ears can take throughout his/her life.
It would be interesting to see a spectrograph of the horns’ tones to see what the different pitches and overtones are and why they might have a different timbre.
i dont know if i enjoy the naration more than the content, but keep em coming. Im informed and educated also my curiosity that I didnt know i had, satisfied.!
@@dukeofthedance8062 honestly, have been buying aftermarket horns for years and alway thought they were literally scamming us lol... what i did a few years ago was to go to a Junk/scrap yard and scrap the horns off Mercades/VW cars as those horns are pretty loud and I have been satisfied so far.
I remember fondly my Dad called out to the garage. He said he cleaned out the horn on my 71 Subaru wagon. So I hit the horn. Scared me half to death. Back in the early 80's. My favorite car ever. Handled better than new ones
You should have also bought a train horn from horn blasters. I have a actual train horn in my '21 Elantra N-line. It's insanely loud. Conductors special 844 with the 6 horn upgrade
@@daymianhayes2493 hornblasters, "The Nathan Airchime K-series horns will be the LOUDEST option on the market. These are actual locomotive horns that come off of retired locomotives that produce 149.4 decibels."
I've got a pair of the Hella horns on my van (one of the factory ones died), and as a pair they are plenty loud to do the job, and are well built. Plus they come with a sticker for the back window!
Interesting math on the decibels, I was wondering where you were going with the volcano bit. Makes me also wonder how many decibels my conductors special kit from Hornblasters has. May not be the loudest, but that frequency! Probably why they call em the shocker horns. When you hooked all the horns together it had a similar note though, and still at a cheaper price tag. More horn tests in the future?
Hey, just wanted to let you know that the reason the dual horn and all the horns combined ended up being louder than expected is because that calculator you used to add up the volumes is wrong. It uses the 10dB=10x convention instead of the usual 20dB=10x convention. You can tell this is the case because, as you said in the video, an increase of 6dB means twice as loud, so two 106dB horns should sum up to 112dB, just as you measured, and not 109dB. All the other calculators and calculations you used throughout the video seems to be spot on though. Great video!
Good stuff haha and the commentary and volcano info is what really made this a gem! Thank you for quality vids that you have obviously put some effort into❤ ❤
A new record for dishonest advertising. Guess we should be glad, since we didn't have global destruction from your testing and you guys weren't deafened or worse. Nice job on the Krakatoa reference.
Now you've got me curious, what happens if you hook one of those up to your shop compressor at 150psi? More air = more better, or maybe just more destruction?
Self destruction seems perfectly reasonable for this caliber of device. After all, this is the channel that attached a gas engine with nitrous to an impact wrench. Blowing up a $20 horn doesn't seem to be out of the question
I'd love to see more of these, and If you could add reaction time as a test feature please! I have some air horns that take a full second to fire off an actual note, making them useless for traffic. Would be hepful to know the ones that are more instantatious
That last one sounded exactly like the lightning warning at an old camp ground with a water feature nearby, but just pitched up by ~12%. That one had a lower frequency, but still is LOUD, and could be heard clearly for about 5 miles or so. It's Florida, during summer. We get a lot of storms. You wouldn't want to be near the building that had this thing, as I'd guess it's probably in the neighborhood of ~120 dB. 10 seconds continuous indicates that a lightning strike happened within 10 miles of the area. (Basically a "Get the F out of the water RIGHT NOW!" alarm.) 3 X 4 second blasts is their all clear.
I should note that people heard the blast from much farther away than Perth. It was heard in New York and the British isles. Oh, and IIRC it could be heard 7 times across the globe, not 3.
I had a car once that the horn would only work if the am radio was on. I could make the horn louder or quieter by increasing or decreasing the volume on the radio. However, even at full volume it was as loud as maybe a horn made for infants! It always made pedestrians laugh so I would do it at red lights especially if people were looking miserable. I miss that car. It was always an adventure going from point a to point b because it always felt like it would break down at any moment.
Nice comparison, and liked that you used Hella as a control unit.(Popular brand here in Europe). ^ I wished for the Stebel Nautilus to be on this test list. It is advertised to be 139dB and ca 35 Euros (25 USD) , seeing a lot of clones claiming 150dB.
Customers that bought this also bought, Sure-Blind 1000 Watt halogen headlights, Bootleg Calvin peeing on major automotive manufacturer logo sticker and Truck Nuts. I think its called the Douche Deluxe Package
A great demonstration of inexpensive horns. Thanks for conducting the tests. The capacity of the air pumps may be a limiting factor. I designed a horn (known as a whistle on a commercial boat) system for an 85 foot passenger vessel. I used a 125 psi compressor, a 10 gallon storage tank and 1/2" air line to the whistle. The tank was mounted close to the whistle to reduce losses due to the airline diameter. It also required a pressure shutoff for the compressor and remote button in the wheelhouse to activate a normally closed solenoid air valve. It could be heard from 2 miles distance. As you can see the system would not be practical in an automobile. My point of all this is that if the air horns you tested had more pressure and flow they may have been louder. But of course the cost would be considerably more.
The sequel - LASERS: ua-cam.com/video/ZH3yMeA7HxQ/v-deo.html
We measured at 2m (not 1m) because thats what the horn specs sheets say! The bomb correction should say 10,000X the Nagasaki FatMan explosion. Bonkers. Also the % greater than Hella can be simplified and corrected as (from top to bottom): 1.15X, 1.19X, 1.72X, 2.29X, 2.57X & 1.46X
18650 cells. so many fakes, so many chineseium mAh.
Perhaps pressure washers?
I've had good results with two different horns on my cars.
Both made by Stebel, one is an air horn called nautilus and one is a twin electromagnetic pair called Magnum.
Both claim high noise the nautilus 127db and the Magnum pair claims 115db.
To my ears they are a similar noise level but the nautilus is a high tone air horn type like a stadium horn and the Magnum is a more aggressive "GET OUT THE WAY" type.
@Eric Duckman You know you can just buy some reputable Chinese cells from reputable sites like 18650batterystore, instead of off eBay right? And besides, Project Farm already tested this.
Or are you trying to say they should test how close the actual capacities are to the advertised ones of the reputable 18650s?
Love this video. Definitely do make more car product testing videos and less drill stuff. Donuit media is a gold mine, and they split it 20 ways.
I can’t believe that one horn didn’t actually produce 600dB. I thought for sure that product was capable of obliterating the entire solar system.

I love that we got a history and geology lesson for a joke. We even got math and science lessons in this video. I appreciate the effort and dedication for a bunch of cheap Amazon horns.
The biggest joke was the fact that someone trying to explain something scientific, could not even get the basic math right. 200 Mt is not 20 Kt x 100. 200 Mt is 20 Kt x 10000.
fun fact: emergency vehicle sirens has a range of 110-129 db, 120 db will cause permanent hearing loss at 2 meters if exposed for more then 30-45 seconds and temporary damage if exposed for around 5-30 seconds, this is why emergency vehicles turn off their sirens if they get stuck in traffic and when they pass through tunnels, if they did not they would cause thousands of cases of temporary and permanent hearing damage.
They also turn them off when stuck in traffic to avoid pressuring drivers into panicking and making mistakes that would cause an exponential increase in the number of emergency vehicles needed.
I can only imagine what your neighbors thought when all of them went off at once. Sounded like a comically large crash involving several jingle trucks lol.

An interesting test for sure, but as their tones are not always constructive, interference will usually act to reduce their amplitude. If he had hooked multiple of the same horn up and tested that, there would have been a much greater chance to increase the amplitude. As this is the Torque Test Channel and not a The Who concert, I didn’t anticipate that kind of test. Was still happy to witness it (via VOD), and also happy I was not present even at distance in the industrial park they were testing it in.

60 dB Hurts my ears a bit
The reason 194 dB is the limit in 1 atmosphere is because of the wave troughs/rarefactions clipping into vacuum. So the full wave can no longer form, due to there being no lower pressure than a full vacuum and the opper pressures having to work with 1 atmosphere of air.
Though in reality and with real air an its thermodynamic properties the waves start distorting non-linearily from around 150 dB already.
To get beyond those 194 dB you need extra air-pressure from somewhere. And that somewhere in practical terms is generally an explosion producing a whole lot of localized extra gas volume.
I love that based on the seller's descriptions you're actually testing doomsday weapons. "According to the seller this should wipe out my entire city for 28 dollars, let's test it out."

Not twice as loud, actually; the decibel scale is logarithmic. 600 db is 1*10^29 times louder. So multiply the volume of the eruption shockwave, by the number of people on the earth, and then by the number of stars in the entire universe, and you'll be pretty close to how many times louder 600db is than 310db.

Great stuff.
Something important about traditional automotive “horns” (not the air horns) is that they need to be rigidly mounted to something in order to get their best noise. That’s why some of these sounded so weak. Just sitting them loose on a surface means they lose some of their power.
Regarding the stupid/not based on reality ratings on Amazon, these no-name companies are capitalizing on the ignorance (i.e. stupidity) of the average person and the general mentality of “more is better.” It doesn’t have to be based on reality, as long as it is more “rating” than the competition (and unbelievably cheap), people will buy it.
Regarding mounting, the infamous "beep-beep" Roadrunner car horn from the late 60s and 70s achieved it's unique sound partially through the mounting bracket design.
Unmounted they have an entirely different sound
Especially since Amazon won't police the reviews. Even stopped my ability to leave reviews due to "suspicious" review activity
I don't think it's "stupid" of anyone to think that 300db is 150db x2. It really is just ignorance of the scale that is counter-intuitive to all other everyday units of measurement. It's the same with batteries. Consumers are expected to weed through a legitimate shopping website filled with illegitimate entries, and people of average knowledge/patience/trustfulness can't be expected to always know that there aren't really 6,000mAH 18650 batteries for consumer use. It's straight up scamming people who haven't been given the tools to know better, especially because any research on the subject on a google search is flooded with "TOP 10 18650 BATTERIES" with affiliated amazon links.

Damn, I was looking forward to a horn so loud it would physically move someone out of my way with a shockwave...
hmmm, sth that goes over the speed of sound...
You wouldn't really move someone out of your way with the shockwave, rather you'd remove them out of your way
at 600dB it wouldn't just move someone out of the way with the shockwave. It would release about 1x10^48 Joules of energy. To say that's a lot of energy would be a significant understatement.
It would literally vapourise the solar system into a rapidly expanding plasma (everything, the sun would be blown away by the energy release like you blow flour off a kitchen countertop), it's entirely like a few neighbouring systems would go that way too.
Your "horn", over time, would be easily detectable across the entire visible universe with current technology.
Of course in actuality putting that much energy into such a small item would like mean that it would collapse into a medium sized black hole.
Regardless, someone being in your way wouldn't be biggest problem anymore 😂.
@@hellfiresquid 600db is like a type 1A supernova, lol.
@@peter5.056 exactly, it would remove them
and also remove you, and whatever planet you're on, and probably a lot more.
You will probably find the Hella horn will increase a couple db once it is bolted to a sufficient part of the vehicle & the tone will usually change also. Should have got a truck horn & used a air compressor to see how much louder it is or even with the cheap car horns they usually get a lot louder.
This is one of the most hilarious videos I have ever seen. You've got a very intellectual sense of humor.
I'd have liked to see a Cadillac 4-note horn set tested, since those are by far the loudest (and best sounding) OEM horns I know of. I've pulled a few sets off junkyard cars to put on mine.
The caddy trumpets were the nasty ones
Heck yeah! Those 4 note GM horns are classic and legendary! (Especially if you grew up in the 60's and 70's!) One of my favorite GM commercials is the one where they take a Tahoe with the same horn, and put it on a revolving platter to become the "new" lighthouse! It totally works and trips you out because they slowly zoom in from a very far and wide angle perspective on a dark foggy scene. You just hear the fog horn and see light sweep by. It's not until they get close enough you realize it's a Tahoe rotating on top of the light house with it's high beams on sounding the horn.
I'm sure it's not real, but it still messes with your brain. It was probably just marketed to select regions like mine (New England), perhaps the Great Lakes and the Pacific NW. No one else would get the reference or have that lighthouse sound embedded into memory like we do growing up with it! LOL
In the motorcycle world, the Denali Soundbomb series is really popular, if you do another one of these tests I'd recommend including either their original or split. I've got their split and it is VERY loud compared to a standard motorcycle horn
Oh boy, not only do I get blinded by SUV headlights on low beams by driving a sedan but if this catches on, I can be deafened as well. I wonder what new pleasures await on the road.
I feel like half of drivers have their high beams on permanently now a days
@@FOXCRF450RIDER For sure, but I now think it's SUVs and pickups which are so high that the darn low beam is in your eyes when you drive a normal car. It's horrible and it's dangerous.
LED headlights are almost unregulated now, its ludicrous out there, yellow tinted glasses help me enormously
They rely on people not knowing and understanding log scale measurements. I am a retired test engineer and I have no complaints with your test method. I was in the market for a good horn and the aftermarket claims for dB just left me to keep my stock horns as I knew they were BS. I guess I will eventually get a Kahlenberg KM 165 ship horn with a REAL 143 dB. At 34x18x18 in. it should fit in the back of my RAM Express.
You'll need a trailer for the compressor and tank, though.
A lot of the trumpets themselves have a diaphragm which'll start to rust and cause air leakage, reducing the volume of the horn. I thought my (long gone) airhorns had an issue with the pump, because it'd just whirr away when energised, so after getting an identical set, I replaced the pump. Same dealy! Swapped back everything, so new trumpets with old pump, loud as I got the originals on day 1.
Best I could do to prolong them is to drip oil into the hole where the hose goes, and onto the diaphragm through the sound opening. Then give 'em a few blasts to let the oil squish around and get into the contact area between diaphragm and trumpet.
The pumps also wear around the seals, so cleaning the innards and reoiling should be general maintenance on those beasties, too, even though no one ever brings it up.
considering a theoretical 600db horn, maybe that's what gabriel's apocalyptic angel horn is, just the real version of a $20 horn from Amazon lmao
I need to start making horns and put up a graph against actual explosions to truly scare people in my marketing materials. "Buy our $18 horn and literally blast the cars around you off the planet"!
IIRC the default distance for sound measurement is 1m
Edit: And don't forget - an increase in 3dB does *not* make it double as load. Yes, the effect needed to increase 3dB is 100%, but for sound to be audiable double the strength, you'll need to increase it by 10dB. Interestingly, 3dB is also the limit to which the average person can register a difference (lower or higher). People working with music and similar, can often differ between lower changes than 3dB, but those are mostly exceptons.
Yes and one other thing is the formula for dB correction at a different distance assumes an isotropic source which the horns clearly are not.
The two dual horns likely exhibit what is called constructive interferance, which means their sound waves merge together and make a larger one, making it louder than just the sum of the two horns, or at least my guess
I think constructive interferance can only cause twice the original waveform at max because when waveforms exactly match in amplitude and inverted phase, you get the maximum and that's only double the original.
If the summed waveforms have different frequencies, the resulting oscillation in the sound may be something that the dB meter reacts to but I'm not sure why.
The video didn't mention if the meter used A, B, C or Z weighting. I think the dB calculator on the computer probably matches only the Z weighted meter (which is the only one that actually meters the energy in sound, other more or less try to measure human hearing instead).
i suspect theanufacturer might have made the 2 horns have different pitches on purpose, as having 2 horns with matching pitches would potentially risk destructive interference if for some random reason, one horn starts off with inverted phase.
@@kirkhamandy Yes, if the soundwaves interfere destructively that would result in silence. However, executing this in practice with two sound sources in two different physical locations (e.g. 5 cm away from each other) causes the silence to project "between" the sound sources and lobes of sound diagonal from the projected silence will see constructive interference and double energy (imagine waves in water from two separate objects but in 3D in air).
@@kirkhamandy Yeah, I figured it out from "Schrödinger's Horn" part but the destructive interference was still a good point which is why I added a real comment about it.
bro literally risked the entire solar system by using a 600dB horn
5:35, that calculator assumes sharing same power. 2 horns getting individual power should get +6dB, and they did. Same for speakers. Daisy chain 2 speakers and you get +3dB, give them each power and you get +6dB.
I would love to see how much power each of these horns pull during testing too, especially the ones with pumps.
all of it
Jiggawatt.
This is awesome.
Please do winch line pull ratings next! I need to know if the HF ones are as strong as they claim!
_OOOF!_ , what a great idea but, could be really dangerous for the testers.
Heh, reminds me of working in a powersports dealership. Customer wants a 10,000 lb winch. "Sir, your vehicle only weight 500 pounds." Nope, I gotta have the power to snap my frame in half or I'm not happy lol.
Always remember kids, decibels are logarithmic, meaning a +6 increase in decibels is twice as loud, +20 is 10x, so a 600 decibel horn would be about 10^25 or about 10,000,000,000,000,000,000,000,000 louder than a 100 decibel concert
I went through the waters by Krakatoa While sailing aboard the USS Enterprise CVN 65 and it was one of the most Eerie places I've ever seen in my life.
This might just be my favorite TTC video. The snark is fantastic!
I bought some expensive air horns (a set of 3) awhile back and installed them on my truck. They were rated at 140 dB at 120 PSI and they were loud! If you were standing next to my truck even a short blast would cause you to cover your ears and you could actually feel the concrete vibrate! So you can buy very loud air horns but they cost more than $25 and in my case I had to supply my own compressed air.
A big problem with Amazon is sellers can suggest changes to an items listing.
And other sellers will suggest changes that are completely wrong every time.
New law: horns should sound as loud inside the vehicle as they do outside to discourage drivers from being assholes.
thank you for fixing the sounds to make them easier to listen to, it surprises me how few youtubers edit the audio on their videos in 2022 but im glad to see some people are still doing it 😆😆
I appreciate the audio adjustment, but I really love the use of an actual decibel meter and standardized testing. It's really subjective whenever anyone reviews a horn, exhaust, etc. on the internet. You're often relying not only on the varying quality of the recording equipment, but on the individual viewer's playback equipment and even their personal hearing quality and opinions.
@@rebturtle I agree, a decibel meter is much more accurate than a persons ear, especially with all the damage a persons ears can take throughout his/her life.
It would be interesting to see a spectrograph of the horns’ tones to see what the different pitches and overtones are and why they might have a different timbre.
I laughed so hard after that first horn introduction. You told the story perfectly!
i dont know if i enjoy the naration more than the content, but keep em coming. Im informed and educated also my curiosity that I didnt know i had, satisfied.!
@@dukeofthedance8062 honestly, have been buying aftermarket horns for years and alway thought they were literally scamming us lol... what i did a few years ago was to go to a Junk/scrap yard and scrap the horns off Mercades/VW cars as those horns are pretty loud and I have been satisfied so far.
I remember fondly my Dad called out to the garage. He said he cleaned out the horn on my 71 Subaru wagon. So I hit the horn. Scared me half to death. Back in the early 80's. My favorite car ever. Handled better than new ones
6 months old and I still watch/listen this video. Has me LOL everything. His presentation is what makes it so funny.
You should have also bought a train horn from horn blasters. I have a actual train horn in my '21 Elantra N-line. It's insanely loud.
Conductors special 844 with the 6 horn upgrade
Where can I purchase a real train horn?
@@daymianhayes2493 hornblasters, "The Nathan Airchime K-series horns will be the LOUDEST option on the market. These are actual locomotive horns that come off of retired locomotives that produce 149.4 decibels."
I've got a pair of the Hella horns on my van (one of the factory ones died), and as a pair they are plenty loud to do the job, and are well built. Plus they come with a sticker for the back window!
sticker adds at least 10 DB
Interesting math on the decibels, I was wondering where you were going with the volcano bit.
Makes me also wonder how many decibels my conductors special kit from Hornblasters has. May not be the loudest, but that frequency! Probably why they call em the shocker horns. When you hooked all the horns together it had a similar note though, and still at a cheaper price tag.
More horn tests in the future?
I've come back and watched this video multiple times now. That introduction is just pure gold.
Hey, just wanted to let you know that the reason the dual horn and all the horns combined ended up being louder than expected is because that calculator you used to add up the volumes is wrong.
It uses the 10dB=10x convention instead of the usual 20dB=10x convention. You can tell this is the case because, as you said in the video, an increase of 6dB means twice as loud, so two 106dB horns should sum up to 112dB, just as you measured, and not 109dB.
All the other calculators and calculations you used throughout the video seems to be spot on though. Great video!
Disappointed that my phone speaker still works after watching this video
I enjoyed this, thank you, well done , the part about "God help us all" about the first horn made me laugh pretty good lol thanks for that
Good stuff haha and the commentary and volcano info is what really made this a gem! Thank you for quality vids that you have obviously put some effort into❤ ❤
These companies will complain that you weren't using a proper sound chamber!
The Krakatoa history lesson was amazing, and the smash cut to the train horn was even better. The buildup and the timing was *chefs kiss*
A new record for dishonest advertising.
Guess we should be glad, since we didn't have global destruction from your testing and you guys weren't deafened or worse.
Nice job on the Krakatoa reference.
Now you've got me curious, what happens if you hook one of those up to your shop compressor at 150psi? More air = more better, or maybe just more destruction?
You would probably blow those horns up. Those cheap ones use plastic diaphragms and operate on low psi.
If you can regulate it I would expect to see an increase upto a sweet spot and then decrease. Then possibly self destruct.
Self destruction seems perfectly reasonable for this caliber of device. After all, this is the channel that attached a gas engine with nitrous to an impact wrench. Blowing up a $20 horn doesn't seem to be out of the question
@@gjsmo HAHAHAHAHAHA.....
I'd love to see more of these, and If you could add reaction time as a test feature please!
I have some air horns that take a full second to fire off an actual note, making them useless for traffic.
Would be hepful to know the ones that are more instantatious
That last one sounded exactly like the lightning warning at an old camp ground with a water feature nearby, but just pitched up by ~12%. That one had a lower frequency, but still is LOUD, and could be heard clearly for about 5 miles or so. It's Florida, during summer. We get a lot of storms. You wouldn't want to be near the building that had this thing, as I'd guess it's probably in the neighborhood of ~120 dB. 10 seconds continuous indicates that a lightning strike happened within 10 miles of the area. (Basically a "Get the F out of the water RIGHT NOW!" alarm.) 3 X 4 second blasts is their all clear.
I should note that people heard the blast from much farther away than Perth. It was heard in New York and the British isles. Oh, and IIRC it could be heard 7 times across the globe, not 3.
I had a car once that the horn would only work if the am radio was on. I could make the horn louder or quieter by increasing or decreasing the volume on the radio. However, even at full volume it was as loud as maybe a horn made for infants! It always made pedestrians laugh so I would do it at red lights especially if people were looking miserable. I miss that car. It was always an adventure going from point a to point b because it always felt like it would break down at any moment.
wow this is actually a REALLY good video. It did a great job comparing and explaining decibels! Thanks!
Nice comparison, and liked that you used Hella as a control unit.(Popular brand here in Europe). ^
I wished for the Stebel Nautilus to be on this test list. It is advertised to be 139dB and ca 35 Euros (25 USD) , seeing a lot of clones claiming 150dB.
Customers that bought this also bought, Sure-Blind 1000 Watt halogen headlights, Bootleg Calvin peeing on major automotive manufacturer logo sticker and Truck Nuts. I think its called the Douche Deluxe Package
A great demonstration of inexpensive horns. Thanks for conducting the tests.
The capacity of the air pumps may be a limiting factor. I designed a horn (known as a whistle on a commercial boat) system for an 85 foot passenger vessel. I used a 125 psi compressor, a 10 gallon storage tank and 1/2" air line to the whistle. The tank was mounted close to the whistle to reduce losses due to the airline diameter. It also required a pressure shutoff for the compressor and remote button in the wheelhouse to activate a normally closed solenoid air valve. It could be heard from 2 miles distance. As you can see the system would not be practical in an automobile. My point of all this is that if the air horns you tested had more pressure and flow they may have been louder. But of course the cost would be considerably more.
