Binaural beamforming algorithms for head-mounted assistive listening devices are crucial to improve speech quality and speech intelligibility in noisy environments, while maintaining the spatial impression of the acoustic scene. While the well-known

In real-world environments, human speech is usually distorted by both reverberation and background noise, which have negative effects on speech intelligibility and speech quality. They also cause performance degradation in many speech technology appl

In a hearing aid application, the performance of an adaptive beamformer is sensitive to errors in the acoustic transfer function or noise estimation. The estimation errors can be caused by factors including the head movement of the hearing aid users,

This paper introduces novel two-channel a priori Signal-to-Noise Ratio (SNR) estimators for use in frequency-domain speech enhancement algorithms. The SNR estimation is based on statistics of the noisy phase difference between two microphones in each

In the real world, speech is usually distorted by both reverberation and background noise. In such conditions, speech intelligibility is degraded substantially, especially for hearing-impaired (HI) listeners. As a consequence, it is essential to enha

In this paper, we propose a low complexity beamforming algorithm for binaural hearing aids that achieves a high degree of noise suppression without causing significant speech distortion. Specifically, we incorporate a priori approximate spatial infor

This paper applies blind channel identification (BCI) to estimate direction of arrival (DOA) of sound sources with a pair of binaural hearing aids. It compares the Adaptive Eigenvalue Decomposition Algorithm (AEDA) with the Adaptive Principal Compone
