Is soundwaves effective in extinguishing fire

Tags: Fire. Two former U.S. electrical engineering students have discovered a cutting-edge and unconventional way to fight fires: with sound. Specifically, bass frequencies between 30 and 60 Hz. While the concept of extinguishing flames with waves is not completely new, a handheld extinguisher had yet to be developed and mass-produced.

Sonic Firefighter Extinguishes Flames Using Only Sound

It’s possible. Work by Seth Robertson and Viet Tran shows that you can use sound waves to put out flames. The George Mason University engineering students rigged up a sonic fire extinguisher that …

The purpose of sound wave extinguisher is to find out the range of frequency within which fire can be extinguished. will extinguish the flame of all types and the frequency It helps the fire fighter to fight the fire at early stage. Fire can be range can be measured between 40Hz to 60Hz. Further the extinguished between 40Hz to 60Hz and the …

Can sound waves be used as a fire extinguisher?

Since traditional extinguishers used in zero gravity spray contents in all directions, it’s incredibly difficult to target a flame. But since sound waves can be directed without gravity, using the bass frequencies could be an ideal solution.

Why do sound waves put out fire?

Since sound waves can move oxygen and fire through pressure from their vibrations, this specific frequency of sound wave works to separate the flame molecules from the surrounding oxygen, effectively starving the fire and snuffing out the flame.

How much does acoustic fire suppression technology cost?

Acoustic fire suppression technology is clean and efficient, and devices never have to be “refilled.” The students’ final hand-held, mains-powered prototype, built for around $600, made quite a stir on the Internet and in scholastic circles thanks to its popular YouTube demonstration.

Is it safe to use sound waves without gravity?

But since sound waves can be directed without gravity, using the bass frequencies could be an ideal solution. The students explained that the frequency range used in their technology is within a safe range – unlike weaponized acoustic devices used for riot control or other harmful ways – is completely safe for humans and wildlife.
