舱室空间个人化双耳听音环境仿真

Simulation of Personalized Binaural Hearing Environment in Cabins

双耳听音环境仿真是设计和评价建筑或舱内声场的重要技术手段。为考虑人体生理差异对仿真效果的影响,在测量数据的基础上,利用多元回归分析和一种优选的数据库匹配方法获取与听者生理参数相匹配的个人化头相关脉冲响应,再结合由软件计算得到的声场脉冲响应以及声源干信号完成双耳听觉仿真,获得了良好的效果。

Simulation of binaural hearing environment is an important approach for the design and assessment of sound fields in buildings or cabins. To consider the differences among persons, the multivariable regression analysis and a selected database matching algorithm were used to predict the personalized head-related impulse responses based on the measured data, then the predicted data were combined with the calculated impulse response to simulate the binaural hearing environment. The listening tests show that this method can effectively model the sound filed in a cabin.
