Abstract:
In order to get the mathematic model of a noise control system in space, which is the impulse response of a speaker–microphone system, a square impulse modulated by a single frequency signal has been used. In the paper, a pseudorandom correlation identification method is used to get the impulse response of a MIMO speaker microphone system in the spatial field. The dynamic process and the time delay of sound waves in the spatial field and speaker coils are presented exactly. The model is used for digital simulation and a space sound experiment using a developed adaptive filter algorithm presented by the authors which is the recursive algorithm with interlacing cycle and increasing phase. The sampled noise signal from the motor driver cabin is used as the input of the system. The simulation and the experiment have proved the correctness of the model and the effectiveness of the developed adaptive fillter algorithm.
