Abstract

Previously, we proposed a Two-Stage BinAural Speech Enhancement (TS-BASE) approach for hearing aids in adverse environments. In the proposed algorithm, the interfering signal is estimated by cancelling the target signal through an adaptive filter in the first stage and a time-variant Wiener filter is then applied to enhance the target signal given the noisy mixture signals in the second stage. In this paper, we will briefly introduce the proposed TS-BASE algorithm and then focus on the comprehensive experimental evaluations on its speech enhancement performance and its ability of preserving binaural benefits in non-stationary multiple-noise-source environments. Experimental results show that the proposed algorithm outperforms the traditional algorithms in reducing multiple-interfering signals and preserving the ability of sound localization.
