A dual channel speech enhancement technique for hands-free applications is presented. The proposed method is based on the difference between the powers of two received signals in near-field condition. The subtraction of power spectral densities of noisy signals at two microphones is employed as a criterion for noise reduction. Obtained results show the capability of the proposed method in various noisy environments.
