Abstract
A headphone system is provided that includes a left and right earpiece having a left and right microphone, respectively, to receive left and right acoustic signals and provide left and right signals for processing. The left and right signals are added to provide a principal signal, and the left and right signals are subtracted to provide a reference signal. A detection circuit compares the principal signal to the reference signal and selectively indicates whether a user is speaking.
