中文摘要：

双扬声器系统的一个典型应用就是实现局部范围的双耳声回放，其目标是在听者每只耳朵处回放相应通道的声信号，需要解决的最重要问题是消除两个扬声器发出信号的串扰。为达到此目的，需设计串扰消除滤波器。通用的串扰消除滤波器是通过对声源到人耳处的传递函数矩阵求逆得到的，其面临的显著问题是会导致较为严重的频谱染色。频谱染色会带来诸多负面效应比如系统鲁棒性变差、最佳听音区范围的缩小和动态范围损失等。本文重点研究基于实测传递函数的两种串扰消除优化方案，通过实验在频谱染色和串扰消除方面对两种方法的性能进行对比，并进一步通过双耳时间差的计算分析判断回放系统的有效性。

英文摘要：

One of the most important functions of the two‐loudspeaker system is to realize stereo playback in a specific region .Through sending the ipsilateral channel of stereo signals to the corresponding ear of the listener .The fundamental challenge is to cancel the crosstalk of signals from two loudspeakers .Usu‐ally ,crosstalk cancellation filter is employed based on the inverse of the transfer matrix from sources to ears .Nevertheless ,common used crosstalk cancellation will cause severe spectral coloration which brings many negative effects ,e .g .weakening system robustness ,shrinking sweet spot area and losing consider‐able dynamic range .Therefore ,two different regularization methods based on measured transfer func‐tions are investigated .Experiments are carried out to compare the integrated performance of the spectral coloration and the crosstalk cancellation performance .Interaural time difference （ITD） is also utilized to validate the efficacy of the improved stereo sound reproduction system .
