本文提出了一种在双耳助听器中保持残馀噪声的耳间时间差(ITD)的降噪方法。本文提出了多通道Wiener滤波器(MWF)中的耳间相干(IC)概念，该概念用于保持扩散噪声场的空间主观感觉，以保持和强调方向噪声源的ITD双耳线索。结果表明，前人发展的MWF-ITD技术可以降低处理噪声的原始IC幅值，从而增加输出信号的耳间相位差(IPD)的方差。结果表明，MWF-IC技术同时最小化了与ITD严格相关的输入输出IPD差的非线性函数，并保持了参考麦克风捕获的方向噪声的自然相干性。客观测量和心理声学实验证实了理论发现，表明MWF-IC技术提供了相关的降噪，同时保留了原始的ITD主观感知和对定向噪声源的原始偏侧化。这些结果对助听器设计者尤其相关，因为它们表明MWF-IC作为一种降噪技术，在1.5kHz以下的频率下为扩散和方向噪声源提供了剩余噪声空间保留。

英文摘要：
This work presents a noise reduction method with perceptually relevant preservation of the interaural time difference (ITD) of the residual noise in binaural hearing aids. The interaural coherence (IC) concept, previously applied to the Multichannel Wiener Filter (MWF) for preservation of the spatial subjective sensation of diffuse noise fields, is proposed here to both preserve and emphasize the ITD binaural cues of a directional acoustic noise source. It is demonstrated that the previously developed MWF-ITD technique may decrease the original IC magnitude of the processed noise, consequently increasing the variance of the interaural phase difference (IPD) of the output signals. It is shown that the MWF-IC technique concomitantly minimizes a nonlinear function of the difference between input and output IPD, which is strictly related to ITD, and preserves the natural coherence of the directional noise captured by the reference microphones. Objective measures and psychoacoustic experiments corroborate the theoretical findings, showing the MWF-IC technique provides relevant noise reduction, while preserving the original ITD subjective perception and original lateralization for a directional noise source. These results are especially relevant for hearing aid designers, since they indicate the MWF-IC as a noise reduction technique that provides resid-ual noise spatial preservation for both diffuse and directional noise sources in frequencies below 1.5 kHz.
