Abstract
A system is provided to protect a loudspeaker () by controlling a level of an applied audio signal. A control signal is generated by applying an input audio signal () to the collective operations of a gain control system (). The gain control system () uses the input audio signal () in conjunction with at least one parameter to derive an estimated stress associated with the loudspeaker (). The estimated stress is compared with a protection threshold stress (). If the protection threshold stress is exceeded, a gain applied by a gain component () is selectively adjusted to modify the input audio signal (). The resulting gain-controlled audio signal () is employed to drive the loudspeaker ().
