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
