Notice of Retraction: The study on simulating binaural room impulse response

Abstract

Binaural room impulse response (BRIR) describes sound transfer process from sound source to two ears of listeners. It includes effects of both the hall and the listeners diffraction on sound waves and thus plays an important role on the auralization technique. This paper takes a real concert hall as an example, based on measured room impulse responses, sound energy stream responses and binaural room impulse responses, probed into feasibility of simulating binaural room impulse response based on head-related transfer function (HRTF) and measured reverberation. The simulated BRIRs were then compared with the measured BRIR in time domain waveform. Room acoustic parameter of interaural cross correlation coefficients, IACCs, were calculated from both the simulated and measured BRIRs respectively. The simulated BRIR and the measured one were then convolved with dry musical signals respectively to prepare the binaural music sound signals used for subjective listening test. It was shown that the simulated BRIR is consistent well with the measured one. For the rapidity and easily changing of the simulating BRIR, the method describe here for establishing the simulated BRIR can be applied to the auralization and subjective listening test.
