I want to know what frequency the speakers were sending the sound waves, and what program can genarate that frequency.

Here is an article in Time Magazine talking about Charles Kellogg’s voice made a gas flame “…flare up, turn from yellow to blue and roar.”
The article goes on to say “Sufficiently intense vibrations would have extinguished the flame.”

A change in color was not produced on the show, therefore, they are using the wrong frequency.

When I find the frequency, I will post it all over the internet. Then, we will have smoke detector that actually extinguish the flame rather than just annoy everyone.

I tried this at home and it works you just have to be closer then you were. I’m actually doing a project on this ……. So fore me it worked i gess it depeneds were your standing and how low you can go with your voice….

On the subject of the trombone with the firecracker in the bell; the story you were trying to duplicate included the trombone player’s lips being burned, but when you set up the experiment I didn’t notice if you plugged the mouthpiece to simulate the player’s lips covering them. Could this have made a difference in the outcome?

@ notak.. you are right
I thought the same thing.
The flame was placed 2 inches away from the speaker.
the speaker was moving back and forth probably an inch and creating wind to put out the fire (more wind then noise).
do the same thing but with the speaker 5 feet from the flame it wont budge

Having said this.. I could move a car with speakers. place 50 speakers of I dont know 30 inches each and blast the volume and wow look at that.. I moved a car.
broke all the windows around but look it moved.

in regards to sound and its ability to extinguish fire… you must first understand what sound actually is… and it is vibration of air molecules, more specifically the compression and rarefaction of air molecules… this action can create a “wind” effect at extremely high levels, but it varies on a few things, one of which most specifically is the size of the transducer (that which converts electrical (or some other energy) to mechanical energy)

so to say that wind is putting out the fire is correct, but that “wind” is indeed the sound being created

unfortunately it will be a difficult thing to test because of the fact that it is difficult to steer sound waves as there are mostly omni directional, so distance is the easiest way to control its dissipation

i think finding an opera singer, one who controls the the “distance” of their voice would be far more beneficial than an A Capella group

In my school we are doing a science fair, and I would like to try one of your myths. Can you give me some data about sound waves extingushing fire.

thanks

can you send me an e-mail with the info of the voice extingguisher. because at school we are doing a progect?scince-fear on carbiondieoxide and my grup would like to try it

thank you
