| Abstract(in English) | Accuracy verification of azimuth estimation of sound image was performed by applying the frequency domain binaural model to audio listening environment in car cabin. Accordingly, the new azimuth estimation model of in-cabin sound image was proposed by examining further high-accuracy for this model. Here, extraction of physical feature quantity related to azimuth of in-cabin sound image with the gammachirp auditory filterbank improved the estimation accuracy. As a result, the proposed method has a higher correlational relationship with estimation values and experimental values than the conventional method. Therefore, the results suggesting the effectiveness of the proposed method were obtained. |
