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 said local noise signal and of at least one transfer function per ear, and active matching means (70) co-operating with said position sensor in order to keep each transfer function used in preparing each control signal representative of the path to be traveled by said anti-noise.
摘要（中）：
一种噪声处理装置（D），包括至少一个局部噪声声音传感器（30）和至少一个具有支撑件（11,12）和至少一个声音致动器（21,22,21'，22'）的声音系统。 该装置还包括用于确定人的头部的位置的位置传感器，连接到本地噪声声音传感器的至少一个处理单元（40,40'），以接收本地噪声信号并且被配置为向每个声音传送控制信号 致动器（21,22,21'，22'），所述控制信号是所述局部噪声信号和每个耳朵的至少一个传递函数的函数，以及与所述位置传感器按顺序协作的有效匹配装置（70） 以保持每个传递函数用于准备每个控制信号，代表通过所述抗噪声行进的路径。
