Abstract: Process of extinguishing, expansion, and controlling of the fire flames by acoustic action, where utilizes the pressure alteration causing rarefactions and compressions in the particles generated by the acoustic waves in a combustible, oxidizing, or mixed environment. The factors that influence the control of the flames intensity are: AMPLITUDE, the FREQUENCY and the STANDING WAVE MODE. The standing wave produces two effects: the node and the womb, so the position of the node we get the flame extinguished and the position of the womb to increase the flame. When the rarefactions frequency and amplitude are greater than the burning rate then the flame is diminished until it is off. When the resonance occurs (?=?0) between the flame's natural frequency (?0) and the sound emitted (?) there is the combustion extinguishing, when (?) is close to (?0) there is an increase of flames (?0).
