Abstract
Directional sound location is used to determine security events of a security system. A sound sensor reports a vector direction to a sound source of an acoustic signal. If the vector direction is historically observed at similar times, then perhaps the sound source is not considered a security event. However, if the vector direction is unknown or unfamiliar, the security system may infer the security event and notify emergency services.
