That is using the electrode method to disrupt the flames, not the speaker/sound extinguisher which is what I thought this thread was titled about?

Of course, there is the flip side; the data accumulated
can be used to increase the efficiency of combustion.
There is no speaker- the sound comes from the rapid air pressure disturbances in the candle flame itself, controlled by a high voltage current modulated with an audio signal and passing through the fire plasma.
In 1857, Irish scientist John Tyndall discovered that he could extinguish a candle flame with his voice. This was possible because sound waves are created from the energy of vibrating objects.
