WebOct 21, 2015 · An effective low complexity binaural beamforming algorithm for hearing aids Abstract: 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. WebAn efficient beamforming scheme for wireless binaural hearing aids is proposed that provides a trade-off between the transmission bit rate and the amount of noise reduction. It is proposed to transmit only the low-frequency part of the signal from one hearing aid to the other, which is used in a binaural beamformer to generate the low-frequency part of the …
