AI总结:

本文提出利用包含球形麦克风阵列和球形扬声器阵列的声学多输入多输出系统,通过优化清晰度与直达混响声比来修改房间声场混响特性,并在仿真与听音实验中验证了混响与去混盲效果及对系统辨识误差的鲁棒性。

摘要:

本文提出了利用可调指向性扬声器(由紧凑型球形扬声器阵列(SLA)实现)来修改房间内声场混响特性的方法。这些方法基于清晰度和直达混响声比的最小化与最大化。仿真研究表明,这些方法实现了对混响的显著修改。所研究的系统包括一个球形麦克风阵列和一个 SLA,构成了一个多输入多输出系统。此外,还研究了这些方法对系统辨识误差的鲁棒性。最后,通过听音实验验证了混响与去混响结果。

英文摘要:

Methods are proposed for modifying the reverberation characteristics of sound fields in rooms by employing a loudspeaker with adjustable directivity, realized with a compact spherical loudspeaker array (SLA). These methods are based on minimization and maximization of clarity and direct-to-reverberant sound ratio. Significant modification of reverberation is achieved by these methods, as shown in simulation studies. The system under investigation includes a spherical microphone array and an SLA comprising a multiple-input multiple-output system. The robustness of these methods to system identification errors is also investigated. Finally, reverberation and dereverberation results are validated by a listening experiment.
