Abstract
A glass breakage detection method, constituted of: receiving a plurality of audio samples; estimating low frequency power values of the received plurality of audio samples; estimating wide band power values of the received plurality of audio samples; responsive to the estimated wide band power values, determining an amplification value; responsive to the estimated low frequency power being greater than a predetermined threshold, amplifying a function of the received plurality of audio samples by the determined amplification value; comparing the amplified function with a predetermined function of sound of breaking glass; and outputting an indication of the comparison.
