Fire needs heat, fuel, and oxygen to survive. Sound waves (especially low-frequency ones) can disrupt that balance. By generating strong, directed pulses of low-frequency sound (~30-60 Hz), the speaker pushes oxygen away from the flame’s base. No oxygen, no combustion. The prototype was built using off-the-shelf audio equipment and successfully extinguished small open flames, like alcohol fires, without chemicals or residues. This innovation came from Seth Robertson and Viet Tran, engineering st

But what is that noise?👇 When firefighters go into a fire, they wear self-contained breathing apparatus (SCBA) to protect them from smoke and toxic gases. Built into the SCBA is a personal alert safety system (PASS)—a motion alarm that activates if the firefighter stops moving for a certain amount of time.

These NASA engineers found a way to put out fires using sound waves! As the method, developed by Sonic Fire Tech, uses deep bass frequencies, too low for humans to hear, to literally shake the fire apart. 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. They do require a special kind
