Abstract
Example embodiments may include one or more of receiving sound emissions signals from channels via sound emitters, controlling the sound emission signals, via relay circuits, and one of the relay circuits is configured to interrupt one of the sound emission signals associated with one of the sound emitters while the other sound emissions signals pass to the other corresponding sound emitters, and receiving, via a sound detection circuit, an electrical ambient sound signal based on ambient sound sensed by the one of the sound emitters responsive to the interrupted one of the sound emission signals.
