Abstract: Apparatus and a method for temporarily disabling the operation of a noise-producing electrical device or internal combustion engine upon detection of a predetermined awareness condition, such as an incoming telephone call, doorbell ring, security system alarm or other awareness condition. For disabling operation of an electrical device, the apparatus includes a command module and one or more switchable power receptacles that respond to a control signal from the command module, de-energizing the electrical device, when at least one of the predetermined awareness conditions is detected. Control signals are communicated to the switchable power receptacles via either a radio frequency signal, or by a modulated signal that is conveyed over an alternating current electrical power circuit to which the command module and switched power receptacle(s) are connected.
