Abstract
An audio system may include an audio transducer, a thermal protection subsystem configured to protect the audio transducer from overheating, and a control subsystem communicatively coupled to the thermal protection subsystem and configured to receive an audio signal for playback at the audio transducer, determine an audio heating metric indicative of a predicted effect of the audio signal on the audio transducer, and control operation of the thermal protection subsystem based on the audio heating metric.
