I suppose that depends on how loud you're willing to go and whether or not they can do a directed sound thingy, like the crowd dispersion sound weapons that police sometimes use when they're out of ammo
Serious question: what frequency? Bec what we hear might be around 600-800Hz and that's def not a low frequency (for soundguys). That raises the question if the sound we hear isn't the original sound bec low frequencies (~40Hz f.e.) do have much more energy what would be much more useful that the freq we've heard. Plus if you wouls use the more energy low frequencies the mobile mic wouldn't have recorded the sound at all bec they're not able to record this low. So why do they call it low...
...frequency when it isn't. Why using a higher mid-frequency when the lower is more useful? Or is the sound in this vid manupilated? That raises the question why recording a vid redoing the sound and not telling ppl about it?
That enclosure is doing a lot of work here focusing the pressure wave into a column. Fun for small fires but this is not an alternative to blasting with water
These dB dragraces are insane. Theoretical maximum sound pressure level is 194dB (given 1 bar environmental pressure, you could, theoretically, fluctuate between zero and 2 bar which equates to 194dB) and I think they are up to 184 dB. Yes the scale is logarithmic, so they are still a factor of 10 removed from the maximum, but the achievement in itself is still insane. While it WILL make you deaf eventually, your ears can handle a lot more in the low frequencies that are used in these cars.
Yes, these kind of soundlevels combined with the low frequency can be seen as a fluctuation in airpressure. Sticking your fingers in your ears prevents this airpressure from getting to your eardrums, so most of what you still hear after this is the rattling of your bodyparts (compare the new 'bone conducting headphones' that are widely available). Might still cause dizzyness or nausea as it affects all of your body. See Mythbusters brown note episode although I think they focussed on lower freqs
Imagine doing this and then the rest of your life all you is hear is eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee etc, for ever
This is part of the weirding ways that we will teach you. Some thoughts have a certain sound. That being equivalent to a form. Through sound and motion you will be able to paralyze nerves, shatter bones, set fires, suffocate an enemy or burst his organs.
And yes also extinguish fire if you really have to.
I think it's probably a little more complicated than that, if you blew air at that concave pan with accelerant in it hard enough to extinguish the flame it would flare up and probably splash out.
"By targeting specific frequenciesâbetween 30 and 60 Hzâthe students were able to separate oxygen from the burning surface, snuffing out fires without the use of water or chemicals." https://www.emergent.tech/blog/sound-waves-to-put-out-fire
If it was some burning wood or paper (Class A fire) Iâd agree with you. They are burning flammable liquid (Class B or K if thatâs cooking oil) which would spread out of the pan by a simple puff of air. Basically the speaker reverberating is sucking and blowing much like your mom.
I think the theory behind it is a little more complex than that. You see, the fire is plasma, so, as any form of matter, it haves is own particles and they have their natural frequency. So if you reach the correct frequency you can produce interesting effects on plasma, like laminar flux (to make real light sabers for eg.) or, in this case, disable the fire's behavior. So, we can say that he turned off the fire by "Not Vibing" with it ;P

I think it's probably a little more complicated than that, if you blew air at that concave pan with accelerant in it hard enough to extinguish the flame it would flare up and probably splash out.
Yep, easily found "The sound waves, officially called Infrasound pressure waves, knock oxygen molecules out of the way before the fire has a chance to use them for combustion. They can extinguish fires from up to 10 feet away, and even prevent fires from starting in the first place."
Yes? But it's not blowing a steady stream of air or we would see the fire flame out of the pan. It probably disrupts the draw of air into the pan and caps the pan with combusted gases being prevented from moving up.
i think the uniqueness is that it's not a steady stream of air in one direction like a fan but basically wiggling the air in place really fast. it's blowing AND sucking, not just blowing.
