摘要：
A noise treatment device (D) comprising at least one local noise sound sensor (30) and at least one sound system having a support (11, 12) and at least one sound actuator (21, 22, 21′, 22′). The device also includes a position sensor for determining the position of a person's head, at least one treatment unit (40, 40′) connected to the local noise sound sensor to receive a local noise signal and configured to deliver a control signal to each sound actuator (21, 22, 21′, 22′), the control signal being a function of the local noise signal and of at least one transfer function per ear, and active matching means (70) co-operating with the position sensor in order to keep each transfer function used in preparing each control signal representative of the path to be traveled by the anti-noise.
