    • Periodic first vibrations generated from the engine are reduced by the interference with the second vibrations generated from the speakers disposed in the vehicle compartment of the vehicle. The second vibrations are set in a cycle unit of the first vibrations, and they are corrected (optimized) on the basis of the signals from the microphones detecting the vibrations within the vehicle compartment and the transmission characteristic between the microphones and the speakers. During a transient period of time during which the cycles vary (during which the data lengths of the data of the second vibrations vary), such as by acceleration or deceleration, the data on the vibration wave form of the previous vibrations is corrected in anticipation (i.e. the data length is corrected), the current vibration wave form is set. The correction of the data length is made by inserting a given number of estimated data values into the previous data length or by deleting a given number of the data values from the previous data length. Further, the data length can be corrected by extending or contracting the previous vibration wave form as a whole so as to provide the data length in accordance with the current vibration wave form.
    • 通过与布置在车辆的车厢内的扬声器产生的第二振动的干扰来减少从发动机产生的定期的第一振动。 第二振动被设置在第一振动的周期单位中,并且它们基于来自检测车厢内的振动的麦克风的信号和麦克风和扬声器之间的传输特性被校正(优化)。 在循环变化的瞬时期间(第二振动的数据的数据长度在此期间变化),例如通过加速或减速,先前振动的振动波形式的数据被预期地校正( 即数据长度被校正),设定当前振动波形。 通过将给定数量的估计数据值插入到先前数据长度中或通过从先前数据长度中删除给定数量的数据值来进行数据长度的校正。 此外,可以通过将先前的振动波形作为整体进行扩展或缩小来校正数据长度,以便根据当前的振动波形来提供数据长度。
