Claim Text:
1. A device for treating noise in the proximity of the head of a passenger of a vehicle, the device having at least one local noise sound sensor, the device also having at least one sound system for generating an anti-noise, each sound system being provided with a support and at least one sound actuator carried by the support, wherein the device comprises: a position sensor for determining the position of the head of a passenger; at least one treatment unit connected to the local noise sound sensor to receive a local noise signal, the treatment unit being configured to deliver a control signal to each sound actuator, which control signal is a function at least of the local noise signal and of at least one transfer function per ear and relating to transferring soundwaves between a sound actuator and a passenger; and active matching means co-operating with the position sensor to keep each transfer function that is used in preparing each control signal representative of a path to be traveled by the anti-noise, wherein the support includes respective support means for each sound system, with each support means carrying at least one sound actuator, and the active matching means including a movement system for continuously moving each support means as a function of the position of the head of a passenger so as to keep each transfer function used in preparing each control signal representative of the path to be traveled by the anti-noise.
