Measuring and reproducing spatial impressions of a sound field has been an important issue in auditorium acoustics for the study of existing auditory spaces. For this purpose, the directional impulse response, which contains spatial information, can be measured and auralized. Typical method for synthesizing binaural impulse response from the measured data assumes each reflection as ideal impulse with measured time delay and level. This makes difference between auralized situation and real situation because the shape of each reflection contains the information of sound color. We propose improved auralization algorithm, which uses real reflection samples from measured impulse response. In this paper, we measured the early reflection profile of a room using 5-microphones system and synthesized the binaural impulse response using proposed algorithm.
