In this paper, a method for picking up sounds located in a particular range of angles is proposed. The structure of the method is based on beamforming with postfiltering. The main part our proposal is introducing a scheme to estimate the power spectra of both desired signals and noises, which are used to derive the Wiener postfilter. From the results of some experiments in a reverberant chamber, we have confirmed that the proposed method succeeded in suppressing more than 10dB of the noise level even in a practical situation. ©2008 IEEE.
