Using Sound as a Fire Extinguisher

In this video, I show you how sound can be used to put out fires.

Imagine firefighters throwing a rave party every time there's a fire

Audio Engineer here. I saw a video of the Swedish Air Force putting out a forest fire by detonating a bomb or missile in the airspace above.
The concussive force of the explosion extinguished the fire.. it's a fascinating application of the physics of controlling the motion of air...
now I gotta watch that video again. it's so badass!!

Imagine calling the fire department and instead of sirens you hear dubstep getting closer.

Imagine a fire starts and someone just goes "DROP THE BASS!"

[warpatato]

Imagine a fire truck pulling up to a house fire strapped with a giant speaker and extinguishing the flames with sick dubstep beats

Maybe this is why fire force has such beefy sound effects

Can you put that speaker+vortex cannon combo into a smoke-filled chamber? It'll probably create some funky standing-esque waves, but I can't predict what they'd look like or how far they'd extend.

This actually seems kinda useful maybe for 0g firefighting in the future? Since putting water, CO2 or foam on stuff is way more difficult when you have to make it stick and can't just rely on gravity

I dont know what compelled you to think this was an indoor activity

I work at an injection mold plant. A person working the press had a part come out on fire. The parts are made of nylon. He used a compressed air hose to try and put it out and the part was soft from the heat and he blew flaming nylon on the press and started a fire haha!

When I was a kid in the 80s, I remember my dad telling me about a dream he had. There was a forest fire, and a bunch of helicopters with huge speakers hanging off that were somehow extinguishing the fire. What a weird thing to dream. Later he decided that they must have been microwave dishes, and set out unsuccessfully to invent a way to extinguish fire with microwaves instead. ¯\_(ツ)_/¯

“HONEY GET THE SPEAKER, THE KITCHEN IS ON FIRE!”

“T-THE WHAT?!”

I would love to see how this concept would work when applied with a Rotary Subwoofer since they're capable of moving an even greater volume of air on a household scale.

Dubstep firefighters sounds like a show I'd watch.

My nephew loves experimenting with fire and screaming. This is a perfect experiment for him! He needs to stop researching so much information about cadavers and true crime and focus more on the wonders of science. I just know that one day he will be a great firefighter, especially once he shifts his focus to loud fires and not missing pets. -Lenny

Incredibly fascinating experiment. The whole idea about manipulating sound to diffuse fire is amazing. The potential of science never ceases to amaze.

[Jurtaani]

We desperately need to get a giant subwoofers onto our firetrucks. 😂

[Maisonier]

But what's the best frequency to put out the fire? Or does the best frequency change based on the flame's size and other factors?

[deiaruthers]

Every day I learn wild new stuff on YouTube.I’ve never seen anything like this 😮.

So happy I guessed the reason the speaker worked vs the fan. To be fair, I love car audio. I've messed with speakers all my adult life and know how they work physically. It still amazes me how electricity and magnetism interact. I will never get over how amazing that is.
