The technology behind Sonic Fire is simple. To protect a house, it routes infrasound waves from a generator through ductworks that sit on the roof’s ridge and under eaves. On the ridge, the sound waves fire down the pitch to catch any fire that might start in debris in the gutters. Under the eaves, they are aimed toward the ground to suppress flames that pop up near the walls, catching bushes or branches on fire.
The system turns on when sensors detect flames — even from a cigarette — producing a thumping sound that breaks down the oxygen that feeds a flame. No earplugs are needed.
In October, the startup raised $3.5 million in funding from a group of investors.
