520			_aIn recent years, finding quick and environmentally safe ways to put out flames has taken on particular importance. The acoustic approach to flame suppression is one of the most promising. Since acoustic waves can travel through solids, liquids, and gases, they can theoretically be used to put out fires of many types. The technology mentioned can theoretically be used to put out B-class fires when gases or liquids are on fire. The investigations that are now available have only been done with low-power acoustic extinguishers. Therefore, there is a theoretical and practical void in this area that must be filled. As a result of the activities, new methods for putting out fires employing high-power loudspeakers attached to acoustic extinguishers were developed using image processing. The main goal of this paper is to present the possibilities of using image processing to detect fires as well as the findings of research on the extinguishing of flames with the use of sine waveforms with Amplitude Modulation (AM) for several frequencies, which is also a scientific novelty, including the minimum acoustic power and sound pressure level as a function of a distance from the output of the acoustic system. Based on this, it was possible to calculate the minimum power sent to the extinguisher and the minimum sound pressure level that produces the extinguishing effect at specified input parameters – class A, B, and K fires.
