摘要： A method determines a bias reduced noise and interference estimation in a binaural microphone configuration with a right and a left microphone signal at a time-frame with a target speaker active. The method includes a determination of the auto power spectral density estimate of the common noise formed of noise and interference components of the right and left microphone signals and a modification of the auto power spectral density estimate of the common noise by using an estimate of the magnitude squared coherence of the noise and interference components contained in the right and left microphone signals determined at a time frame without a target speaker active. An acoustic signal processing system and a hearing aid implement the method for determining the bias reduced noise and interference estimation. The noise reduction performance of speech enhancement algorithms is improved by the invention. Further, distortions of the target speech signal and residual noise and interference components are reduced.

摘要： A pure aluminum outer layer is provided to facilitate bonding with aluminum bonding wires having a diameter of 50 .mu.m or greater without formation of troublesome slivers upon bonding. Beneath that a copper-bearing aluminum layer with 1 to 4% copper content is provided. A third layer beneath the copper-bearing layer containing up to 1% silicon can be added below the copper-bearing layer to promote adhesion at contact window edges.
