Concerned that your mixtape is so fire that it might endanger listeners? Well you can now extinguish the same flames with booming sonic waves. Two engineering students at George Mason University invented an extinguisher that uses sound to fight fire. By blasting waves through the subwoofer, a fire is overwhelmed. See a video demonstration just below:

With considerable amounts of research, two final-year undergraduate engineering students, Seth Robertson and Viet Tran, invented the device. The device is a development of a concept demonstration done by the US Defense Advanced Research Projects Agency (DARPA). The acoustic fire suppression technique they developed is below.

The device works because sound waves have the ability to manipulate the ability of oxygen to interact with burning material. A fire requires both of these things, and the sonic waves interrupt the oxygen getting to the fuel. This is of course only if you get the right frequency of sound for the interruption. The students found that low-frequency bass sounds were the best option. So apparently dubstep isn’t dead; it could very well be used to fight fires in the future. For more specifics, check out the graphic below.

As this was an undergraduate research project, there is truly no telling what the future of this could be. The prototype itself only cost $600, but is also only effective against small scale fires. So don’t stock up on Skrillex just yet to go fight some fires. For now, you will have to stick with spraying white foam. No not like that, get your mind out of the gutter.
