Every time lightning strikes, a huge assortment of stuff is released. We're all familiar with the usual flash of light and sound, but what you probably didn't know is that lightning releases a huge burst of radio as well. This type of radio, known as VLF radio, is some of the strangest there is. By converting this radio directly to sound we hear a cacophony of sounds, from pops and click, to animal like chirps and even strange sci-fi sounding noises. There's lot of other phenomena that can also produce VLF radio like this and by learning what each sound is, and when to listen for them, you can learn a lot about what's going on on earth.

The dynamic range of your interest is incredible , never a dull topic and always well documented.
I used to listen to VLF a lot. The trick was to either go to a desolate location (freeze to death in a car late at night) or use a repeater to send the sound to a more convenient place. It is very hard to predict the occurrence of VLF emissions and whistlers, therefore one should just record all night and later look at the spectrograms to reveal the interesting events. These days Audacity on any computer with a sound card can easily record for hundreds of hours at a time.
The picture shown at 7:40 is pretty humbling.
This is the real-life equivalent of the Minecraft thunderhack
Never expected something real to sound so sci-fi or lofi lol
Whistlers are so cool
@1m27s: "khz" No, it's 'kHz' (uppercase 'H'). It because the unit is 'Hz', with a lowercase 'k' for kilo in front. For those interested, the next one is 'MHz', then 'GHz'; in those cases the 'M' and 'G' are also uppercase.

As a child, I used to go to the clearest AM radio station if storms were near and listen for loud crunches in the signal. Would give me an idea how powerful the thunderstorms coming were.
Me too!
Same!
ב''ה, pretty much every receiver ever doesn't need a carrier present for this; some detail on how the broadband noise 'emulates' one to result in the audio output would be a nice demonstration of receiver theory.
Every video is like science paper or a bachelor's diploma. You're a very motivated man, wish you luck and never lose your enthusiasm and curiosity)
When I used to have a 27Mhz cb radio, I liked to switch it on during a thunderstorm and listen to the lightning coming through the radiofrequencies. I could also hear the whistles from sunspots or solar flares and chirps from cosmic rays hitting the atmosphere or magnetosphere.
sounds that go “TWEEP!” linearly when you receive with single sideband are likely ionosondes

While growing up, my dad had a portable SW/MW receiver, and I loved finding sferics.. found great amusement, great memories
7:27 I like that you're using future Earth with a flooded Amazon and Greenland and no Florida.
I wish I'd gone with an amazon on fire instead tbh.
@@thethoughtemporium The flooding will maybe make it into a nice inland swamp after it's all been burned? ¯\_(ツ)_/¯
Do we, as a planet, really need Florida?
tbh eliminating florida gets me hyped for glacial melting

Oh man you did a video on the thing that got me into HAM radio! One book I've found that is basically an atlas of things you see in VLF is "Whistlers and Related Ionospheric Phenomena" by Robert A. Helliwell. Dover sells reprints on it and I definitely recommend it to anyone into VLF. It covers everything from whistlers to sferics.
Conspiracy theory: Justin is a machine, and none of the sounds were biological in origin.
What art style is that pfp? It seems vaguely reminiscent of “the true story of the three little pigs” and the illustrations in that book collection.
I've been fascinated by the idea of listening to electromagnetic signals for years. For those interested, it seems to be possible to hear the noise local lightning makes by tuning to an otherwise empty spot on the AM radio band. In my car, I've picked up what I think is the noise of lightning (sharp bursts of static), the hum from powerlines, and noises from those vehicle-detection loops in roads. And a handheld AM/FM radio will pick up stuff like the noise from switch-mode power supplies quite nicely, too.

Spark Transmitters! Were the first experiments in radio transmission.. can also create broadband noise which interfere with technology. I made one when I was about 12 in the 80's with an oldschool relay and battery with an aerial wire attached, vibrating in a soundproof box to annoy my new stepdad watching HIS show on my (family room) TV. haha.. all through his show, the screen would be static, but my channel was perfect.. (turned relay spark transmitter box off) hehe.
You can also see the RF of thunder/lightning using an SDR tuned into the HF spectrum.
Even easier: Hook up a loop of wire into your sound card's microphone input.
So, back when I had to study all this we never actually covered atmospheric wave guide propagation and your explanation has me wondering if a soliton packet could be injected into it and whether data could be modulated into it. Have you seen any literature referencing such a feat?
This might be obvious but... if you're making it of course you can. If it's naturally made I wouldn't imagine there is an easy way to do so. The sub communication is fascinating and most of their communication is done on ELF. Extra Low Frequency. A lot of time and money was put into it back when we had the polaris missile (nuke capable) on the trident sub as a first launch capability near the end of the cold war. For its time it was very impressive. It also included a 11 mile long antenna array in colorado you might look up. You might enjoy it.

4:50 So lighting has been sending tweets long before any human ever did.

What do you mean by "living under a magnetic field line"? the lines are as far as I know just a visualisation tool and you're always "under" one
he ment it more in teh sens that you have to be near the poles where they so to say enter the gound more since the signals follow the lines.
the densety of the socal feild line is higer near the polses
also if you followed the field line you are under you should be able to find lightning on the other side. Otherwise it wont work
bro why is your name in the middle of your comments age. teach me
If you’ve ever seen ferrofluid under influence of a magnet, you can see that there are regions the fluid congregates towards and forms pointy nodes which depend on the strength and location of the field. The regions and nodes can be remarkably consistent with respect to the location and strength of the magnet. You can almost always predict where the fluid will flow to if you’ve seen the same state (of the magnet wrt. the ferro fluid) before. Now, are those places/points of congregation where those pointy nodes show up actual, physical “field lines”? I’m not sure, but it is tempting to call them that.
(edit: typo/parenthesis)
As a kid, I built self-made telephone systems for our home and always wondered about that crackling noise that was on the line. Now I know what they are. Thank you!
But how could you record the vlf signals from that city in Germany, even though it doesn't exist?
(It's a local joke in Germany to claim Bielefeld doesn't exist )
Wait... I thought it was South Dakota that didn't exist. How far does this conspiracy go?
Molise, in Italy, doesn't exist either.
yeah Australia as a whole isnt real either, neither is wyoming
A few years back before their takeover, when Wunderground's Wundermap rivaled professional meteorologist tools and wasn't a steaming pile of bloated garbage, they had an awesome lightning map which showed cloud-to-cloud and cloud-to-ground strikes. I always wondered how that was done. It seemed like black magic to me and I never managed to stumble upon the methodology. Thanks for finally answering my questions. Also, thanks for the links, I'm going to spend a lot of time listening to these in the background.
Lightning, aka "whistlers' mother" . . .
A nice summary focusing on ground-based VLF recordings. I host a historical archive of Steven McGreevy's material at www-pw.physics.uiowa.edu/mcgreevy
Two minor corrections to this video: The "dawn" in dawn chorus doesn't really have anything to do with local time; it's merely a reference to the morning song of jungle birds that the signals sound like. Also, it's my understanding that the VLF emissions don't push away the Van Allen belts, but drain it near the Earth.
Also, if you want to hear similar space audio recorded by spacecraft . . . you know where to look.
VLF is the fundamental principle for all the lightning detection systems we meteorologists use. Lightning tells us a ton about how strong the updrafts and downdrafts are in thunderstorms. Lightning jumps can help predict tornadoes as well.
When i was younger i always found myself listening to MW and hearing the static noise that lightning strikes made. Good times.
A major source of electromagnetic chirps that ligo can also detect. It can affect the mirrors. :$
Nice video, though I miss satellite content. I love seeing you pick up signals from equipment that's hundreds of miles away in space!
Dude you shouldve been my science teacher
Man let me tell you this: Your channel inspired me to create one on my own. Like you said I should in the comment section months ago. You inspire us all with your research and projects. You are much appreciated. Thank you for the QUALITY content. cheers!
Such a chirping also occurs when you strike metal bars, heavy cables under tension, and when MCU Whiplash uses his whips.

At the 3 minute mark just casually make the point that the wavelengths Tesla was working with a century ago do exactly what he said they did. A century ago.
Where was that exactly? I went back to 2:50 and listened for a minute and didn't hear it.
@@johnpossum556 When he's describing the propagation of VLF waves at the 3 minute mark. In his time Tesla was saying he could use VLF to send messages across the Atlantic and because everyone was using hertzean wave mechanics that said EM waves travel in straight lines no one would believe him. Then Marconi used Tesla's equipment to send messages across the Atlantic and claimed he did it first. Despite a massive amount of evidence that Tesla had transmitted signals further over a decade previously.
@@gustavhebner2174 I heard no mention of Tesla in the video.
How can you possibly pick VLF under ocean, when the ocean's salty water is incredibly conductive (and you've mentioned in the beginning that it's a very good reflector)?
A bit later, I thought that while electric field is screened very well by the conductive water, the magnetic field can potentially penetrate a lot deeper. How much deeper? Well, that is called "skin depth", and it can be easily calculated given the resistivity and the frequency. For ocean water resistivity, I found a value circa 0.2 ohm*m. For 1kHz, I calculated the skin depth to be 7 meters. So, a submarine whould be able to pick something up, but only if it is quite close to the surface. Below 20 meters it should fade to nothing.
The conductivity just tips the wave a bit so it can curve enough to not leave the atmosphere, doesn't really impede it, so it penetrates water just fine. Also, not much of the energy of a lightning bolt ends up as VLF. It's enough to pick up, but not a huge amount. Whereas for military stuff they blast copious amounts to get it where it needs to go. Also a lot of the reason radio has issues penetrating the ocean is because of the air water interface. Once it gets past that it can travel further. VLF mostly ignores this interface so it's already in a good position to keep traveling.
@@thethoughtemporium And what's the deal with the interface? Is it too reflective? or too irregular?
As for reflectivenes, VLF seems to be the point where it's the highest, as it is where dielectric permittivity of water is the highest (circa 100, so refractive index is 10). So it's worst for reflectivity. Then in the microwave it drops and gets a high imaginary component, meaning high absorption coefficient. then we are approaching the light territory...
This channel is a freakin' treasure trove. Good job being awesome, keep it up, please!
Can you please cover ULF?
They call it Chidori, Sound of 1000 birds.

अरे गजब।
Fun fact if you take a headphone jack with a very long wire and plug it into the microphone then download a program called saqrx which is vlf software to view it then you can see vlf signals which is pretty cool.
Edit:
I recommend sdrsharp instead of saqrx since sdrsharp has more features
How can you talk about lightening and RF and not even mention the Schumann resonances.
OK so they are not very easy to receive, you need to be in the middle of nowhere, and typically require a low resistance 8 kg (18 lb) coil of copper used as a H-field antenna, with a high relative permeability core (mu-metal or possibly Manganese-zinc ferrite ) to receive ELF (3Hz to 30Hz). www.vlf.it/romero3/ics101.html is a good example, and there is lots of good information on that site ( www.vlf.it/ ) about the reception of VLF (3 to 30 kHz),ULF(0.3 to 3 kHz), SLF(30 to 300 Hz) and ELF(3 to 30 Hz).
is it possible to use the time difference of arrival to locate these lightning strikes?
Yep, though with multiple direction sensing detectors you don't necessarily need to. It requires more precise timings, which are harder to do than simply orienting your detectors north.
Blitzortung.org
Now what are the skirrel/chipmunk/dove/pigeon sounds at 18:10? Anyone knows?
There are even higher pitched chipmunks a bit later.
its fun to connect a small photovoltaic panel to headphones. Then you can hear lightning strikes immediely. Each has very different sound. After hearing for a while you will know what kind of sound will produce a really hefty thunder several seconds later.
Never heard of that before, definitely will try
I use VLF receiver with photodiode. It can pick up lighning, fireworks, small explosion flash ( from fireworks ).
about your geko tape , i found a good sorce of a material suitable as a mold , it is the poralization filter from an lcd montor , i iven had one thst stuck to my closet althoagh i feel like it was more electrostatic related but still
Cool! Have you tried using the grooved underside of a CD or similar media? I hear they have very narrow grooves.
4:08 why does the graph say "Kelvin meter seconds" though. /s
jokes aside i always had mad respect for lightnings, i mean isn't the cloud to earth thing just a giant capacitor? and a lightning is "just" the voltage building up so high that it breaks through the dielectric
I recorded a lightnig too by recording my audio amplifier with a long cable attatched xD But only nearby lighnings are possible because everything else is too silent.
Yep. You can also connect a long wire to your computer sound card's mic input which is very sensitive - works well as a VLF receiver, and you can use an application like Spectrum Laboratory to view the signals. Be careful though, as excessive static voltages on the longwire can damage your computer! I connected mine through a capacitor and a large choke to attenuate higher frequencies that can overload the input such as local MW transmissions (actually the secondary winding of a MOT) and with a bit of playing around, it works very well.
In fact, just google 'sound card VLF' - loads of info out there!
It doesn't work nearly as well as one of the receivers. I've tried it and it mostly sucks. Your computer throws a ton of noise so it's hard to pick out the useful signals and there's no amplification so it's gotta be from a storm much much closer to you. That's actually part of the reason I made this video, I had an old video that uses a sound card and the results are night and day comparatively.
@@thethoughtemporium yes, computer noise sucks. even from a security point of view, as i heard it was possible to extract some information linke keystrokes from that. but as i said, it only works for nearby storms. if you cant see the lightning, you almost cant hear it.
A part of me really wants to get a VLF radio... But another part of me wants a hand held version specifically for man-made VLF emissions. A few years ago, I decided to chain a bunch of transistors together to make a long darlington chain, with a 15cm antenna... Damn, it was so interesting walking around the house with some earbuds plugged in, powered from a small battery and just pointing the antenna at things to hear their radio emissions.
Great video, have always been interested in learning more about the ionosphere, and this also serves as a great update to your previous video about VLF
On the subject of radio, though, what's happened with your SDR stuff? I haven't heard a peep about it in months. You had ambitions plans about rebuilding Pipsqueak and mounting him in a radome when summer came around
Got busy with other things. This is why I stopped making update videos. Beyond no one really watching them, I'd get people excited for a project before getting distracted or busy with a different one. As with all of my projects, I will get to it eventually, but I pick the things that I find the most interesting at the time so I don't get bored and burnt out. That said I have actually been working on it in the background, just hasn't made it into media. Found a place to set it up permanently, but will need to wait for next summer as the season's already basically over.
It makes me a bit sad how oversimplified this is. First of all, it doesn't just "cost" more energy for the electron to spiral around, it stays in the plane of equal electromagnetic energy. Secondly, theres clearly a lot more to the whistler tone than just the length it travels. Otherwise why wouldnt the echos get progressively more stretched out?
These are just the problems i could come up with during a quick watch, who knows what else I missed. I understand its not easy to balance between making a video understandable for a wider audience and giving a proper correct explenation, but the danger of oversimplification to the point where information is flat out wrong is real, and this video left me a bit dissapointed.
On a positive note: very cool topic, thanks for introducing me to it!
The whistlers do get stretched with each successive echo.
@@thethoughtemporium you'd expect the second hop to be twice as stretched as the first one and so forth but the graphs in your video suggest that theres barely any difference
Fun fact: E layer of the atmosphere was the first one to be discovered and they decided to name it E just to have a bunch of letter both before and after it to have them reserved for later use. However, turned out that before it was only one distinct layer (D) and letters A-C ended up being forever reserved and unused. That sounds like some IT standard development doesnt it?
did you already try the shoot-laser-at-moon thing?
I'll now be listening to lightning to fall asleep..
How amazing!!
The things most of us will never know about are just amazing..... wow
Besides microsferics, there's also blitzortung.org.
Sir, thank you for theheads-up.
why has all the ice melted on your earth in the magnetic field diagram haha
I Have a video of listening to a thunderstorm with an AM radio.. They're actually really cool, the next time they have a storm I will make a new video
From the description, these ultra low frequencies make me think of that project the Tesla wanted funding for. Something about a tower that could use the Earth itself to transmit energy, which would be available to anyone with a receiver… I vaguely remember some talk of putting up a lot of them, and making energy available to everyone. Was he trying to use ULFs to achieve this?
Probably. That it certainly possible, but it would most likely give everyone cancer and not be able to enter cities. However if you are interested in this topic I suggest you go research into radio galaxies, as they have quasars in the center that are so powerful that anyone in the galaxy could just build an antenna and get free power from light years away
Whistlers are created by the fact that different frequencies slow down by different rate. So original, short signal had broad spectrum and became stretched due to travel over long distance, right? So why each subsequent, echoed whistler isn't stretched even further?
What he said, why?
@@UberAlphaSirus You meant that my question was not clear enough? Sorry, my english is far from any good :)
Wow the effort which goes into this video is amazing !!
Im a guitarist and my amp makes a weird static noise when a lightning strikes. The weird part is that the sound of the lightning is heard first from the amp.
@James DeGray Digital. I guess its becaouse of some grounding issue.
Lightning generates a spectrum of noise, from the MF to the VLF band. The higher frequency noise pulses are attenuated more rapidly and this is a method of determining the distance to the strike. There are small devices tp clip on the belt for use outdoors, hiking, mountain climbing, golf etc, which detect the MF and LF noise and give an approximate distance.
Just went to that live VLF website and within a few seconds of listening to a station, I heard a whistler
I have a video I made a while back, search for it under: Sound of lightning on the radio 2e0pgs
I instantaneously recognized this sound from the first song on pink floyds album the division bell
It really fit Cluster One!
Dont get struck by lots of electricity. It is dangerous.
Ok thanks
@@mrbenjiboy9527 you are welcome my name of yes.
is it possible to use the time difference of arrival to locate these lightning strikes?
If you have mutliple antennae, yes. Otherwise, how would you know the difference between time and distance?
Yup. Not all the sensors are magnetic based. Should've mentioned that time difference is also used.
That's pretty cool. I have never heard about this before.
A lightning powered Tesla coil would be the ultimate Mad Science Project though too large-scale to be practical, but capturing lightning with a rocket and steel wire seems the sort of thing these guys'd be well capable of, with perhaps a coil gun or the like at the end, we can't all have a Flux Capacitor :) Great video as always of course.
So, can you do with with an SDR? Would you need an LNAs for it?
Lightningmaps.org is a great source.
VLF is 3 - 30khz. RTL flavour SDR's lowest frequency starts at 17 000 000 khz for the one tuner. You could probably up- or down convert it... but... you can use just your plain soundcard, and the same SDR tools... :-) Just plug an antenna into your sound card jack.... :-) Google SDR VLF.
1. 21 gigawatts is not to be trifled with, ask Doc Brown. Great Scott!!
11:50 wtf VLF is purple and commutes???! 😳
I really like your device because it is very sensitive and can produce those sounds, unlike mine, which only rings when it detects a strong electromagnetic wave.
my stomach started to growl at the end so i thought i heard some aliens from the song of the earth...
mine too wtf lmao
Sasuke you will never beat naruto.
Sounds like people cutting down and burning trees in the amazon.
Very interesting, and a great idea to use them for tracking lightning bolts.
Can someone explain to my dumb self why exactly do synchrotron emissions occur? The guy said it's because the charged particle loses energy in a magfield but I'm fairly certain that magfields do 0 work on any charged particle placed within, even ones with initial kinetic energy? So how can there be energy loss from particle if there is no work applied to it?
Conservation of energy. An object in motion stays in motion unless acted on by an external force. In this case the external force is a magnetic field. For the particle to curve it has to accelerate a bit, but that would mean it has extra energy. It sheds the extra energy as synchrotron radiation. The more effort it takes to bend it's trajectory, the more energy in the radiation it emits. Magnets are a form of energy storage and exert forces on things that pass by them.
@@thethoughtemporium Ah, I see. Thanks for the explanation dude
I've often thought since I was a kid, that if we could capture lightning we'd have no need for any other energy source.
You triggered 22 flat earthers
I built a VLF loop antenna and I've been getting these weird hisses that span between 0-2000hz that last about half a second, some as long as ten seconds, some appearing in sporadic bursts of them. I'm still not able to identify these signals, as they don't appear to be lightning sferics as some hisses last ten seconds. What could these sferics possibly be? I'm conjecturing solar activity, but I live in Florida and relatively well protected by our magnetosphere.

Hello from Montréal! That makes me proud of my city. I can see my worksite from up there!! Very nice charnel .

Greetings from Sweden!
You, Sir, just got yourself a new subscriber 🎉
Will digg though your channel in hope of more contents like this
It has become extremely hard to find a radio-quiet location to receive VLF without annoying interference. The FCC and other radio regulatory agencies around the world have really dropped the ball in regulating interference. Power lines have always been annoying because listening to the harmonics of 50 or 60 Hertz spoils the experience. Now almost all of our power supplies are switch-mode so they generate a huge bandwidth and power of electromagnetic garbage. The cat is out of the bag.
I wonder if this what there talking about with sounds like UVB-76 The Buzzer you how Lightning strikes and it triggers the interference on TV from Moscow Russia
2:03 so I found this video while researching whistlers cuz I was watching security camera video from my house of a lightning strike that was close to my house, and I noticed right before the lightning/thunder, it almost sounded like a cartoon missile was incoming
when I emit solar wind, a very low frequency signal can be heard.
Actually, lightningmaps.org gets its data from an open source project that uses TOA (time of arrival) or rather TOGA (time of group arrival) to pinpoint the location of lightning (I think hackaday had an article about the hardware side of things at some point).
If you enjoyed this video, check this one out: ua-cam.com/video/fdj8p6c2lew/v-deo.html
It has samples of multiple different radio signals from lightning.
