Described in detail herein are methods and systems for identifying actions based on detected sounds in a facility. An array of microphones can be disposed in a facility. The microphones can detect various sounds and encode the sounds in an electrical signal and transmit the sounds to a computing system. The computing system can determine the sound signature of each sound and based on the sound signature the chronological order of the sounds and the time interval in between the sounds the computing system can determine the action being performed causing the sounds.
