摘要

In general, it is necessary to establish a new theory taking account of the input dependency of system parameter when the stochastic input signal (different from the input test signal used in a case of the system identification) is newly excited. From this point of view, in this paper, based on the foundation of the previously reported extended regression analysis method with less information loss, a prediction method for the output response probability of arbitrary stochastic acoustic systems is proposed by considering the input dependency of system parameter based on the statistical property of stochastic input signal. Finally the effectiveness of the proposed method has been confirmed by applying it to an actual room acoustic system.
