In recent years, the study of sound source localization in order to suppress the noise becoming actively. But, sound source localization that intended for impact sound has not been performed because the theory of sound source localization has been postulated steady sound. In this paper, we proposed a procedure for sound source localization analysis of impact sound, and compared with the conventional method by experiment. We are evaluating whether to achieve better results for the transient sound source by using the theory that is based on a Near-field Acoustical Holography (NAH), changing the continuous wavelet transform rather than Fourier transform. The results of this study, we observed that expression for the transient sound becomes more appropriate by the NAH after processing with continuous wavelet transform.
