Gunfire or plastic bag popping? Trained computer can tell the difference

Engineering researchers have developed a gunshot detection algorithm and classification model that can discern similar sounds such as gunfire or a plastic bag popping. Discerning between a dangerous audio event like a gun firing and a non-life-threatening event, such as a plastic bag bursting, can mean the difference between life and death. Additionally, it also can determine whether or not to deploy public safety workers. Humans, as well as computers, often confuse the sounds of a plastic bag popping and real gunshot sounds.
