ABSTRACT:
A system for transducer compensation based on ambient conditions includes a transducer, a signal processor and an ambient condition sensor. The signal processor may process audio signals for the transducer. In addition, the signal processor may receive signals from the ambient condition sensor. The signals may represent ambient conditions being experienced by the transducer. The signal processor may dynamically adjust the equalization of the audio signals based on the ambient conditions to optimize operation of the transducer.
