Sound Waves Zap Fires, Saving Homes From Water Damage

Sonic Fire Tech, an Ohio-based company, has pioneered a novel fire suppression technology utilizing low-frequency sound waves. This innovative system generates infrasound waves that vibrate oxygen molecules, thereby starving flames of the essential element needed for combustion. This method allows for fire extinguishment without the use of water, thereby preventing collateral water damage to structures.

The acoustic generator, housed within a building and connected via a ducting system, activates instantly upon detecting heat. Unlike traditional sprinklers that require minutes to respond and can release significant amounts of water, Sonic Fire Tech's system offers immediate action. The sound waves are below the human audible range, ensuring no disturbance to occupants or pets. This technology is particularly promising for grease fires, which water-based systems cannot effectively combat.

While DARPA and university students have previously explored acoustic fire suppression, Sonic Fire Tech's founders, aerospace engineer Geoff Bruder and lawyer Michael Thomas, have advanced the concept. After raising substantial funding in 2025 and 2026, the company is now focused on testing and certification. Experts acknowledge the technology's promise at smaller scales but await proof of its efficiency on larger fires and long-term reliability.

Sonic Fire Tech has secured three permits in Los Angeles County and is initiating its first installation in Altadena, California. The company is also exploring applications for wildfire suppression in collaboration with research institutions. The ultimate goal is national certification, which is expected to begin testing this autumn, with a potential first fire and safety certification in 2027, opening possibilities for widespread adoption in new constructions and existing buildings.
