Abstract
An 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 output. The high-frequency part is generated by a monaural beamformer using only the locally available microphone signals. The trade-off can be attained by adjusting the cutoff frequency of the lowpass filter. For speech sources with a 8 kHz bandwidth in the presence of an interfering source, it is shown that good performance can be achieved with a cutoff frequency of 4 kHz
