Using Sound as a Fire Extinguisher

[@grjim8909]

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

[@dadtype2339]

Funny story, I'm a retired Fire Captain, and we were doing a practice burn, this was an old house that the owner needed destroyed, so instead of hiring a demo crew, or some construction company, here in NC it's possible to have an inspection to make sure there is no asbesto, lol always thought that was an Italian sauce when I was a kid. Anyway after a pass it's given to the fire department so we can practice with a house on fire. Once we are finished with training, we set the house on fire and monitor it but we allow it to eat the entire house safely. So, now that you have an understanding, we were doing one of these and the location was by a freeway and there were a couple of homes thankfully far enough away from danger but still, the owners came out to watch. Well we had Bud water, it's a special can of Budweiser that is filled with their water and it's given out to Fire Departments and the like, it looks like a can of beer, blue and white has BUD on the side big and bold, even comes on a 6 pack plastic grouping, ha!so me and the crew we're all drinking away on our Beer Water as we called it...and it pulled out from the crowed watching us, our first Practice Burn Karen!!! Oh she was yelling and screaming about how we should all be ashamed drinking beer and putting out a fire, what sort of an example are we setting, she was Karen Level Queen and so annoying but we laughed and kept drinking, and so she comes through and gets in my face while I'm drinking a Bud Water and she asks for who was in charge I said me, I had a Chief there but I'm running guard here lol. I'm sipping away while she yells, Ahhhh, I gasp out harshly and tell her I can drink these all day like they were WATER! Hoping she would see as I also showed her. Well that did it, she was calling the police and sure enough out they came and of course it's a small town we know each other I explained and lol the Sheriff deputy looks around we are standing or sitting but all have a bud water in hand raising it up Cheers Brother! He laughs and says oh those! Karen meanwhile is going berserk! Especially when he takes a one we crack it open and slam our cans together and we throw back he tries to show her it's water, I do the same and then she slaps the can but her hand misses and hits me in the face! I said okay enough with her, I said remove her please. And with pleasure the Deputy tossed his can and quickly took hold of her, well she resisted and whipped her head back and head bunted the Deputy caused his nose to bleed, well accident, or not, he arrested her and off she went. We held our cans high as they left. So, when I say your comment it reminded me of our Beer Water and Karen. Hope you are well, have a great day and thanks for reading ❤

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

[@Tacheonblack]

That's a pretty interesting application. If you're in a 0g (or, more accurately, microgravity) environment, odds are good there's no air outside, so you could just vent the oxygen until the fire starves. But, sound waves would be a neat way to spend a vehicle's electrical power (via speakers) to fight a fire while conserving the oxygen needed to replenish the room.

[@martianingreen]

@@Tacheonblack I thought more about the inside of a spacecraft or like larger space station if you don't just instantly wanna go to venting the entire atmosphere

[@Azilythe]

Extinguishing fires via sound only works because the fuel is bound to the ground via gravity, with the heat and exhaust rising due to density. Flames in Zero G are weak as a result, but are still dangerous nonetheless. Agitating the fire in zero G would likely only work to make the flame stronger. The best way to extinguish fires in Zero G remains venting the oxygen from the burning room.

[@V3RTIGO222]

The thing is that there's no O2 in space (enough for a fire that is) except what we bring up there. It would probably be better to vent the oxygen temporarily to stop the fire. Zero G fires are extremely scary because gravity doesn't stop it from expanding in all directions very quickly. I think a large speaker device might be a bit impractical in Zero G as well.

[@GeorgeWashingtonLaserMusket]

Modern fire control systems for sensitive area's use a gas that's denser then air so you just fill the room and it suffocates the flame out. Sound would be tricky at best to knock a fire out in a data center but using non-flamable dense gas is super effective.

[@oleg4966]

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.

[@kingcosworth2643]

You wouldn't get standing waves without a reflecting surface and a freq high enough to become directional. Under around 120hz soundwaves become omnidirectional, it's why bass sounds like you are enveloped by it but you an tell the source of a symbol crash. Also, the tuning of a bass reflex enclosure means that above 120hz there is no sound being emitted from the port, it's acting as solid wall with this tuning. Most cabinets are tuned around 20-40 hz so it this freq the sound emitting from the port is 180deg out of phase with the driver, as the freq climbs the port becomes a restriction until essentially so soundwave can pass. So, yes, you can do what you envision with a reflecting surface, just not with a standard audio tuned bass reflex cabinet.

nah, he did the fan dirty, he didnt even try to put a cone over the fan so the air would be directed to the fire JUST LIKE THE CONE OVER THE SPEAKER. Its just a bad comparison and bad science.

[@maudiojunky]

I can provide a little more detail on how the bass reflex port works. Speaker design is all about modifying the phase of the waves coming off the speaker cone, not providing airflow. The speaker cone emits positive waves off the front and negative waves off the back (180 degrees or pi radians out of phase), and if these waves meet they cancel out. If you run a speaker in open air it will have no bass response and the high-frequency response is determined purely by the dimensions of the speaker cone and your position relative to it. In a sealed speaker you contain the rear wave of the speaker and get a slowly-declining bass response, with the air inside the box acting as a spring which changes the resonance of the speaker and naturally protects the speaker from moving too far and breaking at low frequencies. In a bass reflex (ported) speaker the air inside the speaker box still acts as a spring at most frequencies, but now the plug of air contained in the port acts as a mass which forms a resonator that gets excited by the wave coming from the rear of the speaker cone. This is exactly the same thing that causes an empty bottle to whistle when you blow over the rim, a helmholtz resonator. The resonance of this system determines what frequency range will be boosted, which is accomplished by delaying the waves coming off the rear of the speaker so they're in-phase with the waves coming off the front of the speaker. This only works for a narrow frequency range, below which the speaker will put out less bass than a speaker with a sealed back because waves grow longer at low frequencies and the time delay from the helmholtz resonator is constant, thus the sound waves from the rear of the speaker cone will be out of phase with the front again at low frequencies (the useful range is where the waves are less than 90 degrees or pi/2 radians out of phase). The air inside the box no longer acts as a spring at very low frequencies, so ported speakers are more vulnerable to being damaged by driving them at bass frequencies below their tuning, and if the air in the port becomes turbulent the output level can suddenly hit a wall or even drop, along with a lot of distortion. The overall effect is a ported speaker can produce more bass in a certain range than a sealed speaker or use less power to do so, but you can't get as deep of bass safely out of a ported speaker as a sealed speaker without making the ported speaker very large and when it hits its limits it's very audible. For how this relates to the experiment in the video, the speaker will work better from the front at a different frequency than the rear. The velocity of the air coming out of the bass reflex port will be maximal at its resonant frequency, and the speaker cone will actually move almost zero distance at this frequency, so the velocity of the air at the front of the speaker will be minimal when it is maximal from the bass reflex port. If you want maximum velocity from the front of a reflex-loaded speaker, you need to use a frequency that's either below or above the resonance of the port, preferably above to operate it safely. If you can reach the front of the speaker cone, then you can find the port tuning by ear if you turn the speaker off and tap lightly on the speaker cone - it will ring at the port tuning frequency just like an empty bottle.

[@akubertanya9704]

amazing.. thx for explaining this very tehnical

[@johns6795]

It would be interesting to experiment with this by blocking the port and trying to put out with speaker drivers on front in new video. A study on which frequency range works best for different fires would also be good in follow up.

[@maudiojunky]

@@johns6795 Yeah I think it's an open question right now whether the period of the wave matters or if you just want maximal velocity. It would be hard to test with a single speaker system unless there's an overwhelming effect from frequency because of how the physics works out for the speaker box. You'd want an overpowered system which can put the fire out across a wide frequency band to record the amplitude needed at each frequency, then compute the air velocity from the speaker parameters and recorded inputs/outputs.

[@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?

[@marlonvillanueva6986]

I have this question too. I thought he would try different frequencies later but he kept using the same frequency. But then, I remember that sound ports are designed to work with a specific frequency so that's why he needs to use only one frequency.

[@royhsieh4307]

it sounds like a frequency made within a range of typical backyard generators, lets say somewhere between 800hz and 2500 hz

[@netflixandchinchilla]

I'm assuming the process of how this whole thing works is by moving air molecules in such a way that areas of rarefaction (low pressure) basically 'snuff out' the flame. I would say lower frequencies would work the best in this case as lower frequencies have longer wavelengths and thus larger areas of low pressure.

[@dl6519]

Fun stuff!! Maximum air movement through a bass reflex port occurs at the port's tuning frequency, and is actually TWICE as much air movement as the front of the cone(s) because the Helmholtz resonance has a phase-inversion characteristic. At the port tuning frequency the cone movement virtually stops and the air in the port is what moves. Also, the rattly distortion you hear with the air cannon might be the woofers' suspensions going non-linear because the air cannon permits airflow out of the port more easily than airflow back into the port, in effect "sucking" the cones inward, and out of their linear excursion range.

[@rshone99]

The issue with battery pack fires is the battery pack itself becomes damaged and the massive amount of potential energy is shorted out. The fire is a symptom of the problem and putting it out without fixing or disabling the short will do nothing which is why currently the best they have is to down the whole battery pack in a big bath to just flat out prevent ignition. Some battery packs catch fire weeks or months after being damaged.

Probably not, fire is just a reaction that has reached a point of ignition which is a function of heat energy. Alcohol is probably an ideal example here because it will interrupt the evaporation and it will not continue to burn. Alcohol will just not remain hot enough to auto ignite(420 Celsius and alcohol evaporates at 78?C) as what does evaporate will burn immediately. Burning like this it is somewhat self regulating. Some house fires can reach, I *think* 1500 Celsius or more for some furniture foams and what not and what would happen is this fire would continuously re ignite - maybe for DAYS. There is nothing better than removing this heat than water so I would not count on it. Also - water can be hilariously bad for these kinds of liquid fires making this example an even more ideal counterpoint to drowning this situation with a fire truck.

Hmm wonder if we can make a firefighter suit to emit this frequency to keep the fire off them. Like a shield

[@Ciesiam]

I was hoping you’d give a demonstration on how sound could put out active flames of a fire. The flame would go out, but you would still have the hot embers which could still catch fire. I guess the initial firefighting would be done by sound and second wave of Water or foam or whatever the cause would be. Thoughts? I absolutely loved your video!

[@KanzakiZD]

putting off fire with a fire music is actually fire 🔥

[@RJ-jg6jx]

Imagine a firefighter come to the scene with spongebob's jellyfish jam on maximum volume.

[@CR055FIRE]

based on the proven effectiveness shown in this video, i recommend all people replace their fire extinguishers with party speakers

[@Quantum39Prime]

4:15 i think that the fan it just provides more oxygen to the fire.

[@Tera_GX]

On episodes like this I'd love to see you make a note about the safety measures you take. I know your setup is already plenty safe, but it's good to be teaching that even experienced people don't rely on confidence alone.

[@libtrs838]

I would guess most people don't want a decent portion of the video to be about safety precautions and setup.

[@Tera_GX]

@@libtrs838 Correct? "My daughter has the fire extinguisher, just in case" is barely 2 seconds?

[@Gracken-k5e]

It would be really cool to implement this into firefighter gear

me too

really good if u cant find some beer just cook some alchohol and drink it up yum yum yum

[@somecsguy9824]

Your production quality is skyrocketing. Loved the firefighting speaker 😂

[@Nobe_Oddy]

The PORT that you are calling the 'Bass Reflex Port' is actually just the PORT... the Bass Reflex "port" is the rectangular ...umm... ... thing... above it... a Reflex Port is just a membrane that is able to move back and forth like a speaker and adds just a little bit extra 'ummpfh' to the bass... it's totally sealed and doesn't let air move between the outside and the inside of the speaker cabinet.... the Port you refer to is just an opening in the speaker cabinet that has a tube that just stick into the inside of the cabinet and ends with the smooth conical shape you see on the outside... this allows the speakers to move more freely as per their design and the tube acts as a wave guide which tunes the sound to be more like what the artist intended because the shape of the cabinet can change this in many ways..... Sound and sound reproduction absolutely fascinates me and the idea of extinguishing fire with sound alow is AMAZING!!! When I first saw that video you show of the two guy putting out a firte with a backpack linked to a tube that you aim at the fire, I ASTONISHED!!! Mainly because I understand how it's performing and it's not that the air is moving the way you show with the open port, it's putting out the fire with the vibrations.... It's kinda hard to explain the difference but I think you're gonna demonstrate this in the rest of the video (I paused it @ 2:30 just to explain all of this... lol) I think it's time to get back to the video :D lmao

[@speakerboy38]

The square thing above the port is the waterproof cover for the mic and usb inputs. The port he refers to is a reflex port and is sometimes called just a port. The "membrane" that you're talking about is called a passive radiator which this speaker doesn't have.

[@iluvpandas2755]

I liked this so more people can see it :)

[@SAGARs_Vlog]

I really appreciate that, u can make thrust from that, that force used in UFO/UAP, but they used sound+vortex in their engine

[@Don.SY-ON]

imagine hearing a dialogue that goes like: "FIREE!! FIREE!!" "get the speaker, QUICK!" lol. could mean different things based on the context and if it's actually a fire.

[@tdata545]

My hypothesis halfway through was sort of right; I assumed the sound detached the fire from its fuel source and caused it to expend the fuel it could hold onto faster than it could resupply itself with.

[@SneakySteevy]

Sound and frequencies are under rated.

[@Kaenguruu]

1:00 Someone needs to create a gif from this

[@iluvpandas2755]

They should. I don’t know how though :(

[@The_DangerZone]

I'll do it.

[@Zilege]

Sick! I actually wondered if soun had any effect on air. Now I know. Thanks dude. 😁

[@uncuttfunk]

I’ve been asking firefighter KZbin creators about why this isn’t being implemented…one finally answered & he’d never heard of it. Our military has technology using sound frequency that can stop a large group of people in their tracks…& make em turn & run…bc they feel their insides heating up. ❤️☀️

[@getaloadofthisguy2927]

I’m sure in the future with enough money and research poured into the technology it could be super effective. But as of right now it seems water is more efficient as putting out fires. Plus the sound may also be distracting to firefighters or people inside burning buildings and may obstruct communication in burning buildings.

[@thenamestails7152]

Firefighters: *holding a giant megaphone* "Everyone, please, don't panic. This is not a drill. Leave the building via emergency doors immediately and organise in the yard. In case of inevitable exposure to smoke stay as close to the floor as possible, apply a wet rug for better respiration. I repeat: this os NO- oh, what? Th.. The fire is gone? But how, it was like consuming half the building?"

[@TeraQuad]

Question: Would sound waves increase the temperature in the room? or make you feel hotter?

[@ihmejakki2731]

Sound is pressure waves, so in the high pressure areas the temperature will be higher. The answer to the second question depends on the music and your dance moves 😎

[@Stealth86651]

Ah, so that's what my neighbors are doing, they're just constantly trying to put out fires all the time.

[@MrSkywalker-s2x]

Yes

[@toeometry5978]

This is the definition of "Energy cannot be Created or Destroyed"

[@gregreee]

“Wiggling the fire to death” is a funny way to put it 😂 I have that same speaker & when you brought that thing out, I was already picturing putting a fire out with my speaker as a party trick lol. Sadly, it wasn’t as simple as it seemed at first ahahaha

I HAVE A QUESTION! I've seen these acoustic sound blast with multiple small cones can lift a tennis ball. So, can audio vibrations be use in a pressurized space station as artificial gravity instead of centrifuge motion?

[@jesse33cdn]

This technology needs to be studied and hopefully used to fight forest fires.

[@bramfran4326]

0:58 best part 😂

[@danniem]

3:11 "vortexes of air" . . . that's vortices . . . "vortices of air". I do have higher expectations for this channel with proper English than maybe some other channels. In a world where it seems more illiteracy is growing rampant, let's hold the line. :)

[@Su-27_433]

"Both "vortexes" and "vortices" are considered correct plural forms of the word "vortex." However, "vortices" is more commonly used in scientific contexts or formal writing, while "vortexes" is often used in everyday language." Chat GPT. Many sites for word "vortex" say that both are correct.

[@JohnCena-le1jj]

@@Su-27_433 Vortices is the only formally correct one, "vortexes" is a purely informal colloquialism. Same with vertex - it becomes vertices, not vertexes. Matrix becomes matrices, not matrixes.

Great episode, I hadn't heard of this before and was fascinated by it and the demonstration you did. I really enjoy your channel.
