To explain the noise from the 10ft pipe edition; I bet you anything the noise is caused by air going from sonic to supersonic flow. The diaphragm is likely causing compression waves to overlap, compressing the air and causing it to go supersonic.
I just wanted to say that I really appreciate all the hard work and awesome production quality that goes into your videos. So many DIY's on youtube are almost painful to watch but yours are always informative and easy to understand. Thank you for the top quality content!
Thank you for simplifying it for us, I’ve looked at other videos and they were making it far too sophisticated to understand the actual workings of the foghorn
I currently use a Bicycle pump connected to and Air Horn that came with an aerosol can . The Horn they use at swim races , I just tossed out the Air Canister and Bungee Corded the Tire Pump and Horn to my handlebars and give it random Toots when I ride around my Neighborhood . But THIS is the kind of thing that would get me into ridiculous amounts of trouble ! Gonna have to build one !
2:33 You should sell that sound sample to a dubstep artist! Or make more of those horns with different lengths of pipes, get a few people to play those horns, and you'll have an acoustic dubstep band!
That 10 foot pvc pipe sound was epic! A couple of those on your truck would really tell people when to get going and that you mean business! Cool video man!
I subscribed to you a LONG time ago when you used to make fireworks. I am happy in the direction your channel is taking though. I have learned a bunch of cool things and I am always excited to see when you post a new video.
Curious, would the sound quality of the horn improve if a rubber sheet was used instead of thin plastic? For example, taking a chunk of balloon latex and using that as the diaphragm.
Love this simple project ! I wonder if you couldn't create something similar to be quickly assembled for a survival situation in a backpack scaled version. Would be way more effective than the small CO² air horns !
I made a version of the large horn myself, it works. The world shall tremble before my mighty roar. No man, woman, or child will escape the sound. Also note that even the large horn does not need a pump, you can blow straight into it just fine and it'll still work.
A great exercise in the acoustics of an air horn. So, extending the length of the exit pipe deepens the sound or do we need to enlarge the size of the T-Piece (horn body)? The long tube had a very warbled (deep sound) effect, would a funnel at the end smooth out the sound? How long does the diaphragm last? This looks like it doesn't need so much pressure to operate like the truck horns on the market that require a bulky (and expensive) reservoir tank. This being the 21st century where everything works at the press of a button, can I use the standard air pump from an old set of musical air horns? Might be a good project for my high school engineering class to explore
Great video as always, and a note to your viewers, the Martian is an awesome book. Well worth buying. I originally bought the kindle version, but it's good as an audio book too. I'm looking forward to the movie they are making about it now.
Hello just wanted to say i love your channel. I love science alot, when i searched "cool science" on youtube you were the first to pop up and ive watched you since 😃
I have an old army signal horn that works just like this. It has a brass plate for the diaphragm. If too much dust gets in it, I need to clean it to make it work again. I will make a short video to show the inside of it if you want.
I built one of these, and it worked fantastically well. I got the best performance using fairly thick vinyl sheeting as the membrane. I also tried to get an ultra-deep tone by attaching 50 feet of rubber garden hose, but since the prototype was lung-powered, I couldn't push enough air to get it to work. Though the couple of times I *did* get it to work, it sounded a lot like your 10-ft-pipe version, only slower and deeper in tone.
The 10ft pipe is like an unwound trombone or bass trombone. It sounds a lot like it too with the lowest note being the fundamental frequency of the pipe.
Hey ! Remember my comment about science that makes what you do actually work ? Well this is the perfect example of a video that (to my humble opinion) woud require a tiny scientific explanation. I'm really interested in what's going on scientifically that makes the air blowing turn into sound waves production. Plus : your "audible" sponsor seems nice ! I'll try listening to one of the audio books, Thanks for sharing.
Thank you so much for this knowledge 🙏 I'm a trucker annoyed that people carelessly cut-off an 80,000lbs Semi. I want a horn that will vibrate their car 🚗 so that they fear cutting-off Semis again. Thus saving future lives. So now I know longer = deeper.
This horn is essentially the same principal as a reed pipe in a pipe organ. Reed pipes can be as short as 1' or as long as 64'. Generally a 64' pipe (which is very rare) can only be felt. A 32' pipe can both be felt and heard. Today such pipes are mimicked by the use of electronics and speakers because of the excessive cost of such pipes. (hundred thousand dollars or more.) In a reed pipe there is usually a very thin piece of brass with a very slight curve along its length. It rests against the side of an open sided tube with a stopper at the bottom. The reed flexes back and forth against the tube (Shallot) All the rest is virtually the same as your horn.
What sort of sound can you get out of this? Would it be somewhat similar to the other diy train horns? I'm not sure that the camera quite does it justice.
Interesting. It looks like the shape of the funnel "bell" has a lot to do with pitch. The difference between no funnel and with funnel on the smaller assembly was about an octave, but the difference in pitch between the small assembly with the black funnel and the larger one with the orange funnel was only about a half-step.
I did a bit of audio editing for the video so don't put too much weight in measuring the differences the funnel makes, but you came to the correct conclusion. The black funnel did a lot more to lower the pitch than the red one did, but the larger horn also started off at a lower note.
Hey one thing that may help for sound variation is a balloon for deeper sound you have the balloon less stretched out and for higher sound more stretched out
Just how much more pressure is needed for very deep tones? I mostly want a deep tone, not necessarily with much bass (easily boosted in DAWs). Also, how would one go about tuning it? Fine adjustments in length?
How does the thickness of the diaphragm affect the horn? I've seen a lot of horns that have 7.5" diameter, 0.09" diaphragms and I was wondering how that would change the sound I get.
@@Nighthawkinlight thanks for replying! I'm going to recreate the Tripod sound effect from the 2005 version of War of the World's and scare the crap out of my neighbors >:)
i read the-"the martian" book, in real life, not in the internet about three months ago and i highly recommend this book, its very interesting, if andi wire reads this, i will like if there will be a part two for this book, maybe when something happens to wattni on the way back home...
Could you make a horn that can have multiple funnels on it? And have it run off of one air supply? Basically I want one that sounds exactly like a train horn.
Oh, nice! I am building one of these with that 10ft pipe extension for my Halloween display. How much volume do you think that air mattress pump is putting out? I want to hook this up to a compressor with an air soleniod, but I don't want to dump just a ton of pressure into this thing.
Did you do any db tests? and whats the highest psi that plastic could handle? Im guessing a heavier material would handle MUCH higher psi and give a lot higher db volume?
you should try connecting a pressure tank to this and put like 40psi in it(so as to not break the plastic film) and connect it to this set up, less pumping and more sound, possibly even a momentary valve to make a tune with it.
The effect with the 10ft tube is rad! I'd like to see you try it with an air compressor and a 4" piece of tube
No doubt! That might be a summer project
NightHawkInLight
Did you try put a funnel at the end of the 10ft pole ?
Zelif I did. It didn't make much of a difference.
I subscribe to you
To explain the noise from the 10ft pipe edition; I bet you anything the noise is caused by air going from sonic to supersonic flow. The diaphragm is likely causing compression waves to overlap, compressing the air and causing it to go supersonic.
I wonder if the long fog horn sound would be the same if you added elbows but ended up with the same length of pipe?

Thanks!
How do you come up with these ideas.. :D
HOW DID YOU GET HERE? XD
I'm seeing many well known people!
Alltime10s! Maybe this video can be used as an inspiration for a new video. Top 10 DIY UA-camrs.
...
+CamTem Other way around. Check the video dates.
NightHawkInLight
You show him! XD
CamTem
Need some ice for your burn?
That's awesome - love it. Now I've just got to remember where I parked my ship!
They're sneaky buggers.
NightHawkInLight 0 to British in three words...
i prefer the britsh guy talking, but cool video!
All I have to do is find where I parked my train.;-)
Thanks dude, my son is now driving me crazy!!!
That last one sounded amazing. It would strike fear into mm late at night.
Then my plan is coming together nicely....
hehehehhehe :P sory for this extra notification :(
Sounds like a Jake brake for a truck!
Moth man?
Sounds like Sasquatch tooting in his pants.
Thank you for simplifying it for us, I’ve looked at other videos and they were making it far too sophisticated to understand the actual workings of the foghorn
That's pretty awesome! Simple to build!
hey why are you here? get back to making awesome videos!
Can u make a review about laser that can burn that people all ready buy please and then make it better in some awesome was
Thanks for the awesome project! For less then $5 we had a blast tonight! Keep up the great work very much appreciated!!
Amazing design!!! I've always wanted to make one but never actually searched how to make. Thanks for making this video!!!
This is an awesome PVC project. What gave you the inspiration for this project?
I saw some videos of cruise ship horns and thought it would be cool to have one.
NightHawkInLight this can be for my science fair

+TerminvsEst Check out Blue Man Group. They are basically that exact thing.
+TerminvsEst he sould connect it as a blow off whistle :P
if someone made a 10 hr version of that noise i'd be happy :)
I need to find a way to fit the last one into my car. I need it.
I haven't experimented yet to see if the pipe can be coiled up with a bunch of elbow fittings for the same result, but I bet it would work!
That would sound epic people would be like WTF was that aha
I was thinking about shoving one in my ass for when I fart.
i bet you could add it to the end of your exhaust XD
Might be able to replace the horn with the funnel and pop it out of the hood, would look badass enough.
Thank you for showing us how the air horn is made! And how the sound is modified!
Using a 16-inch diameter pipe, 29 feet long, will produce the brown note.
The brown note has been debunked, however, a horn that size would likely make you crap your pants due to the sheer volume :P
@@dalegibson9172 should be called the brown pants note.
@@dalegibson9172 save it for Independence Day , why not? You got the right !
Nearly browned meself reading that commemt
It would need a scuba tank to power it lmao
Awesome! I wonder how you'll sneak the 10ft one into a stadium for use during a game. :)
Two foot sections and a bum leg. ;-)
A Bose style sound box in a backpack?
That 10 foot pvc pipe sound was epic! A couple of those on your truck would really tell people when to get going and that you mean business! Cool video man!
The BEST air horn video on youtube. I will make this bad boy!
Great sounding fog horn!
This project is great. I love how they are relatively easy and simply designed.
I subscribed to you a LONG time ago when you used to make fireworks. I am happy in the direction your channel is taking though. I have learned a bunch of cool things and I am always excited to see when you post a new video.
Thanks for keeping with me!
I"m coming across many neat ideas for PVC. This is another I will add to my list. Thanks.
Bob
I made you today and used my air compressor blow nozzle for the air supply. Thank you for making this video.
Curious, would the sound quality of the horn improve if a rubber sheet was used instead of thin plastic? For example, taking a chunk of balloon latex and using that as the diaphragm.
Saved to my Larp playlist. Thank you for the video.
👍🏻👍🏻 I’m going to mount a 20’ length of 4” pvc on my pipe rack and try this when I have some time. Thanks!
I readed this book, its one of the best ones I've bought.
Multiple air compressors all feeding into one GIANT version of this would epic.
Love this simple project !
I wonder if you couldn't create something similar to be quickly assembled for a survival situation in a backpack scaled version.
Would be way more effective than the small CO² air horns !
I made a version of the large horn myself, it works. The world shall tremble before my mighty roar. No man, woman, or child will escape the sound.
Also note that even the large horn does not need a pump, you can blow straight into it just fine and it'll still work.
The last one sounds like Jake Brake!
I said the same thing.
You are awesome I don't know how you do all your projects by yourself
Where do you come up with all of these ideas? You always are coming out with new inventions and creations for us
It takes a while sometimes. I have lots of ideas that don't work right that never get made into videos.
The martian was a great book! I read it a while ago. Cool project!
It was really good. Destin at SmarterEveryDay told me about it. The narration in the audio book is the best I've ever heard also.
It was a great read - with emphasis on "read". I don't care to have others read to me - I don't see the point of "Audible"...

Will definitely be adding this to my car.
Wish I had an old 70's Land barge to put it on.
I wunder why people don't like your videos your videos are like the coolest videos I ever seen. I also shared them to a lot of people.
Thanks!
Great video as always, and a note to your viewers, the Martian is an awesome book. Well worth buying. I originally bought the kindle version, but it's good as an audio book too. I'm looking forward to the movie they are making about it now.
This video was awesome!! Expressly the last one.
I really enjoy watching your videos I wish you posted them more often
Wow, so many famous you tubers commenting. Nice video! I thought it would be harder and more expensive.
Noce work Ben!
I'm really wondering how you transform simple materials into great projects... !!!!!!
Keep going
It's a mystery. Thanks!
Thanks!! Made this today, A rubber glove as a diaphragm works awesome too. The town hears it haha
I read The Martian a few weeks ago. It was a pretty good book.
Hello just wanted to say i love your channel. I love science alot, when i searched "cool science" on youtube you were the first to pop up and ive watched you since 😃
I have an old army signal horn that works just like this. It has a brass plate for the diaphragm. If too much dust gets in it, I need to clean it to make it work again. I will make a short video to show the inside of it if you want.
what kind of psi would that mattress pump be running at. Say if you were to use an air compressor with a regulator
Less than 5psi
I love the sound at 2:20! Would it have the same low frequency if it is a coiled line? That way it will fit under the truck or car.
@KeithFromNY - wondering if you found an answer to this question. I am wondering the same thing.
@@peteypablo1196 Sadly, I bought some of the parts and have not put it together. I will let you know if it ever gets finished.

It sounds like the spaceship from Close Encounters of the Third Kind! I want one of those now!
i am liking this video for 2 reasons reason
1: mass effect reapers were mentioned
2: because it is actually cool
This horn is essentially the same principal as a reed pipe in a pipe organ. Reed pipes can be as short as 1' or as long as 64'. Generally a 64' pipe (which is very rare) can only be felt.

Yep, I am a big kid at heart and love things that make a lot of noise and I have every thing I need for this except the T :)
I might make a version of this that you blow into to make the sound, and cover holes to change the pitch.
Just an idea.
I just beat the Mass effect trilogy for the 9th time this week, and when you did the reaper sound i got chills lol
This is a really cool project I'm excited to try my own hand at making it
WICKED!!!
Great design!
Incredible and simple and awesome and I love this stuff and thank you so much for being in the world
Keep on making awesome videos please I try and attempt all of them

AWESOME!!! something i'm going to do this!
It was a great video, this was my first video I've seen of yours, and I'm definitely coming back for more. Keep up the good work!
Have you experimented with more durable diaphragm materials for longevity?
got yourself a new sub with this. thank you.
Any recommendations for high frequencies? Like 15-20 khz? (I'm getting older, and the dog next door is barking at nothing a LOT)
Im sure the neighbours will love this one, thanks!
Well played, watched the entire sponsor spot because of the background video.
How does the thickness of the diaphragm affect the horn? I've seen a lot of horns that have 7.5" diameter, 0.09" diaphragms and I was wondering how that would change the sound I get.
I'm not sure. A heavier diaphragm probably requires more pressure to function
@@Nighthawkinlight thanks for replying! I'm going to recreate the Tripod sound effect from the 2005 version of War of the World's and scare the crap out of my neighbors >:)
You can make a fiberglass funnel for any size and shape.
Tenkeygeezer said the flare was of Masonite or something.
i read the-"the martian" book, in real life, not in the internet about three months ago and i highly recommend this book, its very interesting, if andi wire reads this, i will like if there will be a part two for this book, maybe when something happens to wattni on the way back home...

DANG at all of the youtubers!
I'm not sure how multiple funnels on the same horn would do, but you can easily run a bunch of horns off the same air supply.
Really cool thanks I'll probably make one oh yeah could you do something on Magnus effect it would be really awesome like a boat or something
+Thurman Humphreys I'll have to think about that one, it gives me some good ideas.
if you used rubber from a bicycle tire instead of the plastic bag for a diaphragm would you get a lower tone?
Oh, nice! I am building one of these with that 10ft pipe extension for my Halloween display. How much volume do you think that air mattress pump is putting out? I want to hook this up to a compressor with an air soleniod, but I don't want to dump just a ton of pressure into this thing.
+Jayson Nickols Connect it with a ball valve so you can adjust air flow to whatever works best.
Can the tone be adjusted by changing the length of the barrel?
ya man
Did you do any db tests?
and whats the highest psi that plastic could handle? Im guessing a heavier material would handle MUCH higher psi and give a lot higher db volume?
Hey Canada, y'all should make some of these to use in Truckistsn 🇨🇦
How would a 90 degree turn effect the sound? Like if not enough room for long horn could an elbow and another section be added?
That was pretty cool! Thanks for making a video.
Yet another great one man, I'd love to see something like that on a truck.
That's pretty amazing, thinking about making one to put in my boat.
Now how do you make a leg horn? Thank you I'll be here all week!
I really enjoy your videos and projects, keep it up!
you should try connecting a pressure tank to this and put like 40psi in it(so as to not break the plastic film) and connect it to this set up, less pumping and more sound, possibly even a momentary valve to make a tune with it.
Your the man! Always posting good vids!
awesome I want to make one for my truck in the future any suggestions on how to mount it?:-) thanks
