Abstract

To improve the accuracy of the sound image localization technique using bone conduction headphones and head-related transfer functions, this paper proposes a preprocessing method using the difference of transfer characteristics between from the entrance of ear canal to cochlea and from transducer to cochlea. The estimation of the differential characteristic is performed using Distortion Product OtoAcoustic Emission (DPOAE) and the preprocessing is realized using finite impulse response (FIR) digital filters. In subjective experiments on sound image localization, it was confirmed that the proposed method improves the localization accuracy compared to the case without preprocessing.

骨传导耳机利用空气传导和骨传导的不同特性进行声音定位

为了提高骨传导耳机声像定位技术及头部相关传递函数的准确性，本文提出了一种利用耳道入口到耳蜗与换能器到耳蜗的传递特性差异进行预处理的方法。利用失真积耳声发射（DPOAE）对差分特性进行估计，利用有限脉冲响应（FIR）数字滤波器对差分特性进行预处理。在声音图像定位的主观实验中，证实了该方法相对于未经预处理的定位精度有所提高。
