Abstract: Nowadays, innovative flame extinguishing techniques are still being sought that do not threaten the environment and do not damage the extinguished elements. One of them seems to be the acoustic method. Research is being conducted in Europe, Americas, and Asia into the possibility of using acoustic waves to extinguish flames. This article presents the original measurement results showing the extinguishing possibilities with a sinusoidal waveform and sinusoidal waveform modulated with a square waveform for the three analysed frequencies (15 Hz, 17 Hz and 20 Hz). A high-powered acoustic extinguisher was applied to extinguish the flames. Such a fire extinguisher may be equipped with an artificial intelligence module. Deep neural networks (DNN) were used for flame detection. Results from the training networks were described, as well as the hardware architecture employed. Such an intelligent module, which allows an acoustic extinguisher to be automatically activated when flames are detected, is particularly useful when traditional sensors are not available.
