Abstract

A protection management unit is described that detects one or more poor performing transducers in a loudspeaker array. Upon detection of one or more poor performing transducers, the protection management unit adjusts driving signals for neighboring transducers to compensate for the reduced capabilities of the poor performing transducers. By adjusting driving signals to neighboring transducers, the protection management unit ensures that a desired tone and spatial response for sound emitted by the loudspeaker array is maintained despite one or more poor performing transducers. Other embodiments are also described.
