Abstract

A first seat noise control device corrects sound collected by a microphone to sound at a listening position of a user seated on a first seat, generates a cancel sound that cancels, at the first seat, the sound of a second seat audio source output from a second seat speaker by using an adaptive filter, and outputs the cancel sound from a first seat speaker. A second seat noise control device corrects the sound collected by the microphone to sound at the listening position of the user seated on the second seat, generates a cancel sound that cancels, at the second seat, the sound of a first seat audio source output from the first seat speaker using an adaptive filter, and outputs the cancel sound from the second seat speaker.
