Sonic Fire Tech has raised $15 million to deploy an innovative acoustic fire suppression system that extinguishes flames using sound waves, eliminating the costly cleanup associated with water and chemicals.
- Sonic Fire Tech raised $15M in a round led by O.H.I.O. Fund and Khosla Ventures.
- The system uses 20Hz infrasonic waves to extinguish fires within seconds.
- Eliminates collateral damage caused by traditional water or chemical suppressants.
- Shows potential in containing volatile lithium-ion battery fires.
For over a century, the gold standard for fire protection has relied on water and chemical agents. While effective at saving lives, these methods often leave behind a trail of destruction—water damage and chemical residue that can result in cleanup bills as high as the fire damage itself. Enter Sonic Fire Tech, an Ohio-based startup poised to disrupt this industry with sound-powered suppression.
The company recently announced a $15 million funding round led by the O.H.I.O. Fund with participation from Khosla Ventures. This capital injection follows a $3.5 million seed round and is earmarked for scaling the workforce and securing critical certifications from the National Fire Protection Association (NFPA).
Why This Matters
BozokMedia analysis shows that the true value of this technology lies in the reduction of "collateral damage." In commercial kitchens, where 75% of businesses fail to reopen after a fire due to restoration costs, a sound-based system is a lifeline. By removing the need for water or foam, Sonic Fire Tech transforms a potential business-ending event into a manageable incident with near-zero cleanup time.
"We are the only technology that creates its own suppressant without collateral damage. False alarms are less of a concern for us."
The mechanics are fascinating: the system utilizes a sound generator that pumps inaudible infrasonic waves (approximately 20 Hz) through ceiling-mounted PVC pipes. Upon detection by sensors, these waves bombard the flames, effectively snuffing them out in seconds.
Beyond kitchens, the startup is tackling one of the most dangerous modern threats: lithium-ion battery fires. While CEO Geoff Bruder admits the system may not fully extinguish a battery fire, it can contain the blaze, preventing the "cell-to-cell" thermal runaway that leads to catastrophic explosions.
| Feature | Traditional Systems (Water/Chem) | Sonic Fire Tech (Acoustic) |
|---|---|---|
| Cleanup Cost | Extremely High | Negligible |
| Response Speed | Fast | Ultra-Fast (Seconds) |
| Collateral Damage | High (Water/Chemicals) | None |
The company is currently developing versions for new constructions, retrofits for existing homes, and even external shields for properties in wildfire-prone regions. The insurance industry has already shown interest, with ongoing discussions regarding potential premium discounts for properties equipped with this technology.
Frequently Asked Questions
Q1: Is the sound used in the system audible or harmful to humans?
A: The system uses infrasonic waves around 20Hz, which are generally below the threshold of human hearing and designed to be safe for occupants.
Q2: Can it completely put out a lithium-ion battery fire?
A: Currently, it is used to contain the fire and prevent spread to adjacent cells, rather than fully extinguishing the chemical reaction inside the battery.
