  • When using a microphone array for hands-free speech acquisition in enclosure environments, one can be faced with the problem of wave propagation in near-field. In this paper, therefore, a near-field beamforming method for microphone array based speech enhancement is introduced which modified subband adaptive beamforming method. The proposed method takes full advantage of spherical nature of the sound wavefront, in which the distance discrimination reduces the effect of reverberation as well as noise on the desired speech signal. Simulations experimental results demonstrate that the proposed microphone array based speech enhancement method exhibits a better noise reduction performance than other methods.
