Abstract(in English) | In this study, a binaural room impulse response that represents acoustic characteristics between a sound source and an ear was analyzed with spatio-temporal frequency characteristics based on a theory of acoustic wave. A spectrum was calculated by using the 2-dimensional Fourier transform on time and space, and spatio-temporal frequency characteristics were visualized and analyzed. In this paper, the spatio-temporal frequency characteristics were calculated with acoustic transfer functions that were obtained by the numerical method and measurements. Moreover, influences of the reverberation on characteristics were examined. From the results, the spatio-temporal frequency characteristics were appeared in the specific frequency band and differed by the measurement conditions. In addition, it was clarified that the reverberation had different spatio-temporal characteristics depending on elapsed time. |
