【摘要】 双耳房间脉冲响应(BRIR)描述了从声源到声接收位置听者双耳处的声传输过程,它综合了厅堂及听者对声波的影响,因而它对研究厅堂声场具有重要意义,尤其适合用在厅堂声场的可听化研究中。文中以一个现实的音乐厅为例,在已测得的房间脉冲响应(RIR)、声能流响应和BRIR的数据基础上,探讨了基于头相关传输函数(HRTF)虚拟直达声、早期反射声的可行性,并将虚拟的直达声、早期反射声组合实验测量的双耳混响声合成了仿真的BRIR,对同一声接收位置的仿真BRIR和实验测量BRIR在时域波形、IACC和卷积音乐干信号后的听感比较后发现,仿真BRIR与实验测量BRIR有较好的一致性。鉴于本文仿真BRIR的方法具有快速、简单易行的特点,文中最后指出,可以将基于HRTF的仿真BRIR应用到厅堂声场的可听化研究中。更多还原

【Abstract】 binaural room impulse response describes sound transfer process from sound source to two ears of listeners,which includes effects of the hall and listeners on sound waves,thus plays an important role on the study of the hall sound field,especially on the auralization study of the hall sound field.This paper takes a practical 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.After comparing simulated binaural room impulse response with measured binaural room impulse response in time-field wave,IACC and listening binaural sound signals convolved with music dry signal for the same position,to a great extent,simulated binaural room impulse response is consistent with measured binaural room impulse response.because of rapidity and easily-complemented of the method simulating binaural room impulse response,the paper finally points out that simulated binaural room impulse response based on head-related transfer function can be applied to the auralization study of the hall sound field.更多还原
