In this study a self-steering beamformer with binaural output for a head-worn microphone array is investigated in simulated and real- world conditions. The influence of the underlying sound propagation model on the estimation accuracy of the direction of arrival (DOA) estimation algorithm and the overall performance of the combined DOA-beamformer-system is evaluated. For this, technical performance...
Multi-channel beamformer algorithms are promising solutions for noise reduction in hearing aids as they exploit the spatial distribution of the interfering signals and therefore in general lead to less signal distortion than single channel algorithms. Beamformers need a priori information about the microphone array and the direction of arrival of the target speech source. For head-worn arrays it is...
