Abstract

Two major objectives of a binaural microphone array system are reducing background noise and retaining interaural relationships, for example, ILD and ITD. Hence, a new adaptive microphone array signal processing based on a weighted least squares algorithm for binaural hearing is proposed in this paper. Instead of Lagrange's method of indeterminant coefficients, which is often used in conventional binaural microphone array systems, a weighted least squares algorithm is employed. Results of computer simulations carried out for purposes of evaluation showed that the proposed method is characterized by flexible and robust adaptivity to various conditions.
