1. A network audio processing circuit, comprising:

  • a first means for receiving a reproduced audio content signal;

    a microphone for providing a microphone output signal in accordance with ambient noise;

    a second means for enabling the microphone output signal during first increments of time when the reproduced audio content signal is substantially off, and disabling the microphone output signal during second increments of time when the reproduced audio content signal is on; and

    a signal processor, in communication with the first and second means for;

    applying a transfer function to the reproduced audio content signal, the transfer function incrementally increasing gain adjustments to the reproduced audio content signal as a function of an increasing amplitude of the microphone output signal, and incrementally decreasing gain adjustments to the reproduced audio content signal as a function of a decreasing amplitude of the microphone output signal; and

    applying an equalization curve to the audio content signal to boost frequencies in a vocal range that enhance consonant perception thus increasing speech intelligibility.
