If the question is referring to the recent story of Students use sound waves to extinguish fire; They have indeed demonstrated that low frequency sound waves can sufficiently disruptive air molecules to put out a small fire, but to me, that’s more of a scaled up demonstration of a subwoofer "blowing" out a candle at extremely close proximity than of anything scientifically …
Students Invent Device using Low-Frequency Sounds Waves to …
The concept works because sound waves are pressure waves. At the right frequency, sound waves can agitate air enough to displace oxygen and extinguish a fire. With $600 of their own money, Robertson and Tran made a 20-pound fire extinguisher out of a sound generator, an amplifier, power source, and a focusing tube made out of cardboard. An …

Could sound waves be used to extinguish fire?
Surely sound waves, just as the explosions (which are percussion waves) such as those used to extinguish oil well-head fires, could work. Considering that the ‘new’ way of describing the ‘fire triangle’ is the fire tetrahedron, this is conceivably possible.
What frequency do fire extinguishers work best at?
While ultra-high frequencies had little effect, the duo found that lower, bass frequencies – between 30 and 60 Hz – produced the desired extinguishing effect.
Can sound separate a fire from oxygen?
If the sound could be used to separate the two, the fire would be starved of oxygen and, accordingly, would be snuffed out. Tran and Robertson explored the impact of different frequencies of sound on small fires.
Do sound waves disrupt the combustion process?
Sound waves can only be disruptive to the combustion process by reducing heat if it was of sufficient intensity – it can not remove the fuel source or the oxygen feeding it.
