A gunshot detection system continually monitors ambient noise throughout a building, learns the building's auditory patterns, and alerts users when sounds are found to be unusual or generally indicative of a dangerous situation. For example, gunshot sensor units positioned throughout the building include microphones. During a learning period (e.g. during normal conditions), these microphones capture ambient noise. The gunshot detection system generates ambient noise models representing the ambient noise during the normal conditions. The gunshot detection system then continually processes currently captured audio data depicting ambient noise (and potential acoustic anomalies) against the ambient noise models to detect and/or identify the acoustic anomalies and to determine whether to generate an alert.
