Abstract

Audio signal processing circuitry in an audio system: extracts a cross-talk signal, which is a component of a second audio signal included in an output of a microphone; extracts a noise signal from the output of the microphone, not including the component of the second audio signal or component of sound emitted from a first-seat speaker, and including a noise component unrelated to the audio system; determines the amount of gain adjustment for a masking noise signal such that the masking noise signal is at a predetermined level greater than the difference in magnitude between the cross-talk signal and the noise signal; adjusts the gain of the masking noise signal output from a masking noise source based on the determined amount; and combines the gain-adjusted masking noise signal and the first audio signal output from a first-seat audio source together, and outputs the combined signal to the first-seat speaker.
