The acoustic extinguisher works by using sound waves—a type of pressure wave—to push oxygen away from the source of a flame and spread it over a larger surface area. These actions break the fire combustion triangle made up of heat, fuel, and oxygen, the three elements required for a fire to burn.

Can sound extinguish a fire?
Two former U.S. electrical engineering students have discovered a cutting-edge and unconventional way to fight fires: with sound. Specifically, bass frequencies between 30 and 60 Hz. While the concept of extinguishing flames with waves is not completely new, a handheld extinguisher had yet to be developed and mass-produced.
Why do sound waves put out fire?
Since sound waves can move oxygen and fire through pressure from their vibrations, this specific frequency of sound wave works to separate the flame molecules from the surrounding oxygen, effectively starving the fire and snuffing out the flame.
What is a sound wave extinguisher and what are its uses?
Although originally developed with household fires in mind, other potential uses for the device’s technology include wildfire settings, automotive shops, in firefighting drones, or mounted in arrays on top of a fire truck. An additional use case for the sound wave extinguisher could be outer space, where fire poses a huge problem.
Is it possible to extinguish fire with waves?
While the concept of extinguishing flames with waves is not completely new, a handheld extinguisher had yet to be developed and mass-produced.
