Abstract(in English) | A new model(Common-Acoustical-Pole and Zero model:CAPZ model)is proposed for a room transfer function(RTF)by using common acoustical poles that correspond to resonance properties of a room. These poles are estimated as the common AR coefficients of many RTFs corresponding to different source and receiver positions. Using the estimated common AR coefficients,the proposed method models the RTFs with different MA coefficients.This new model requires far fewer variable parameters to represent RTFs than the conventional ab-zero or pole, zero model.The acoustic echo canceller based on the proposed model requires half the variable parameters and converges 1.5 times faster than one based on the all-zero model,confmning the efficiency of the proposed model. |
