Hearing aids are expected to help hearing-impaired persons to understand speech especially in noisy environments, which is realized by enhancing the target signal of interest and by the selective binaural hearing processing in human's auditory system. Therefore, an effective system for hearing aids must possess two crucial functions: speech enhancement and binaural benefit preservation. In our previous work, we proposed a two-stage binaural speech enhancement (TS-BASE) approach for hearing aids, in which the interfering signal is estimated by cancelling the target signal through an adaptive filter in the first stage and a time-variant speech enhancer in the second stage. Its effectiveness was confirmed through some simple experiments. To comprehensively evaluate the performance of TS-BASE, in this paper, comprehensive experiments are conducted in various acoustic environments and the evaluations on speech enhancement and binaural cue preservation are performed in terms of objective measures. We report the experimental results along with the general discussions on the TS-BASE performance.
