Abstract

Provided is an "active noise control system and an in-vehicle system" to cancel noise at a plurality of seats using a single microphone (9).A first seat noise control device (3) corrects sound collected by a microphone (9) to sound at a listening position of a sound 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 (2) output from a second seat speaker (8) by using an adaptive filter that receives the sound of the second seat audio source (2) with the sound as an error, and outputs the cancel sound from a first seat speaker (7). A second seat noise control device (4) corrects the sound collected by the microphone (9) 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 (1) output from the first seat speaker (7) using an adaptive filter that receives the sound of the first seat audio source (1) with the sound as an error, and outputs the cancel sound from the second seat speaker (8).
