This New Technology Uses Sound Waves To Put Out Fires In Seconds

April 6, 2026

Fighting fire with sound might sound futuristic, but in San Bernardino County, it’s quickly becoming a real-world innovation that could change how we stop flames before they spread.

The San Bernardino County Fire Department is currently testing a cutting-edge system that doesn’t rely on water at all. Instead, it uses carefully controlled sound waves to put out fires—offering a glimpse at a cleaner, faster, and potentially less damaging way to protect homes.

Developed by Sonic Fire Tech, the system begins by spotting danger early. Infrared sensors detect the presence of flames and immediately activate a burst of infrasound—low-frequency sound waves that humans can’t hear but are powerful enough to disrupt a fire at its core.

Here’s how it works: fire needs oxygen to survive. Rather than removing oxygen completely—which could be dangerous—the system interferes with it.

“We vibrate the oxygen at a rate the fire can’t consume it, and it breaks the chemical reaction,” explained developer Ryan Remington.

That interruption is enough to stop flames in their tracks—sometimes in milliseconds.

Right now, the technology is being designed with homes in mind, offering a potential alternative to traditional sprinkler systems that can cause significant water damage. But the possibilities don’t stop there.

Fire officials say tools like this could one day help slow or even prevent wildfires, especially in high-risk regions. According to the department, the system can create a “protective zone” that halts ignition almost instantly—without the need for water or chemicals.

“This technology works without water or chemicals… and has the potential to reduce fire damage before it starts,” the department shared.

Another key advantage? The sound waves used are completely inaudible.

“We use infrasound, which are sound waves that are inaudible to the human ear,” said Remington Hotchkis, Chief Commercialization Officer at Sonic Fire Tech.

While it’s still in the testing phase, the idea of extinguishing fires with sound alone is already sparking excitement. If successful, this innovation could not only protect homes more efficiently—but also open the door to safer, smarter firefighting solutions in the future.
