At present, the monitoring systems in public places are mainly based on video, but there are blind spots when the line of sight is obstructed, and they are easily affected by factors such as light and bad weather. Abnormal events are usually accompanied by abnormal sounds, which can effectively reflect the occurrence of major accidents and critical situations, and have advantages such as low complexity, easy access, and freedom from space limitations
The technical framework for audio monitoring in public and private places is the same, but the difference lies in the different types of abnormal sounds that may occur.
