| Abstract: | The binaural impulse responses were measured through the 01dB symphonie system and the 01dB dummy head. According to ISO3382, binaural impulse responses were obtained through the MLS technique. The effect of the head was considered during the measurement. The physical and binaural acoustical parameters were calculated from the measured binaural impulse responses. The auralization can be realized through convolution the binaural impulse responses with the anechoic signal recorded in the anechoic chamber. The binaural impulse responses play great role in the auditorium acoustical design. The results can provide guideline to the concert hall acoustical design. |
