Citing a lack of innovation in fire-extinguishing methods over the last 50 years, the Defense Advanced Research Projects Agency (DARPA) last week revealed an ear-buzzing new method for putting out fires: blast it with fine-tuned frequencies.
Officially referred to as “acoustic suppression of flame,” this simple yet potentially revolutionary method simply relies on two speakers playing a specific low frequency toward the fire.
The resulting acoustics increase air velocity, making it easier to alter the origin of the fire’s combustion, also known as the flame boundary layer […]
