Impulsive sound detection and gunshot recognition

Detection of impulsive sounds may be required for different kind of purposes. The first step of sniper detection systems requires the detection of impulsive sounds. Gunshot detection and recognition systems must detect at first impulsive sounds too. For security systems, the detection of impulsive sounds such as glass or door breaking, screaming can be important. Deaf persons can be warned of car horns, alarms and sirens by way of impulsive sound detection systems. The main aim of this paper is the detection and recognition of the impulsive sounds caused by gunshots. Thus gunshot acoustic is investigated for this purpose. The developed methods have higher detection and low false alarm rates than the other impulsive sound detection systems. The proposed gunshot recognition algorithm recognizes the gunshot among the same kind of sounds with very high probability.
