As to individual equalization of differences in HRTFs (Head-Related Transfer Functions) between a dummy-head and a listener for a binaural system, there is a constraint condition that an equalization function must be measured for the listener in the original sound field. In order to resolve the condition, a method to replace the function measured in the original sound field by that measured in another sound field (an equalization sound field) is proposed in this article. Since profiles of the two functions are similar, the original function is approximated by applying ARMA (Auto-Regressive Moving-Average) model to the function measured in an equalization sound field. Experimental results showed that the proposed method was effective for all subjects when the numbers of poles/zeros were 60/60 in ARMA model.
