Abstract
Embodiments relate generally to an active hearing protection device comprising a communication device operable to provide active hearing protection to a wearer; a set of earmuffs connected to the communication device, wherein each earmuff comprises an indicator mechanism operable to indicate to the communication device when the earmuff is inserted into a user's ear, a processor operable to receive information from the set of earmuffs and the indicator mechanisms of the earmuffs, and operable to automatically power the active hearing protection device on or off based on the information received from the indicator mechanism(s). When it is determined that both earmuffs are inserted into the user's ears, the active hearing protection device is powered on, and when it is determined that at least one of the earmuffs is not inserted into the user's ear(s), the active hearing protection device is powered off.
