Abstract:

A method for predicting the scattered sound pressure induced by a three-dimension scatterer is proposed. This method is further used as an error sensing strategy in the active noise control (ANC) system for attenuating the three-dimension scattered radiation. Experiments are carried out to validate the prediction method, and a broadband feedforward ANC system combined with the given error sensing strategy is implemented to suppress an impulsive scattered sound pressure. It is found that the proposed ANC system based on the prediction method is effective, and about 8.2 dB attenuation of the scattered pressure is obtained at the observation point after the active control. © 2012 Elsevier Ltd.
