Intercom systems, installed in many buildings, have both speakers throughout a building, and microphones in many rooms so occupants can respond to announcements. PA and Intercom systems are commonly used as part of an emergency communication system. The term, sound reinforcement system generally means a PA system specifically for live music or performance.
