本文介绍了阵列优化技术的应用,以改善近场响应的任意麦克风阵列。该优化利用了近场和远场声源之间波前曲率的差异,适用于小房间中的混响减少。最佳的近场波束形成器提供了增加的阵列增益从均匀加权延迟和求和波束形成器获得。
This paper describes the application of array optimization techniques to improving the near-field response of an arbitrary microphone array. The optimization exploits the differences in wavefront curvature between near-field and far-field sound sources and is suitable for reverberation reduction in small rooms. The optimum near-field beamformer provides increased array gain over that obtained from a uniformly weighted delay-and-sum beamformer.
