The paper studies the current state of the art in the use of acoustic effects in the prevention and elimination of fires. For this purpose, the literature review method was applied. The well-known approaches to fire extinguishing and their impact on the environment are considered. Multifaceted studies by a wide range of scientists on the possibilities of the acoustic effect in fire extinguishing are noted. The analysis of literary sources showed the negative impact of both the fires themselves and the majority of fire extinguishing agents on the environment. Variants of the use of the acoustic effect for the prevention and elimination of fires of various combustible substances are considered. The influence of the frequency of acoustic waves, scanning speed, power, and other acoustic parameters on flame extinguishing is noted. The possibilities of using a deep neural network for flame detection have been studied. The limitations and advantages of acoustic technology and further prospects for its development as an element of environmental technologies are shown.
