空间声场脉冲响应辨识及应用

Identification and Application of Space Impulse Response

介绍了采用伪随机信号相关辨识法获得空间声场脉冲响应的实验方法，并用多种实验对该方法作了验证．还将此方法应用于空间有源噪声控制，取得了满意的结果．

The method of pseudo-random correlation identification is apppied to iden-tify the space impulse response,and it's proved to be effective and precise. In the experi-ment of active noise control, the good result is achieved by using this method.
