Effect of quantization on beamforming in binaural hearing aids
نویسندگان
چکیده
We consider a beamforming scheme for binaural hearing aids and analyze the effects of quantization on its performance. A limited bandwidth wireless link is assumed between the binaural hearing aids for communication from one ear to the other ear, where signals are then processed using a generalized sidelobe canceller (GSC). We consider the case where observations are quantized before transmission, and study the performance of the GSC beamformer under quantization errors.

On the Impact of Quantization on Binaural MVDR Beamforming
Multi-microphone noise reduction algorithms in binaural hearing aids which cooperate through a wireless link have the potential to become of great importance in future hearing aid systems. However, limited transmission capacity of such devices necessitates the data compression of signals transmitted from one hearing aid to the contralateral one. In this paper we study the impact of quantization...
متن کاملPerformance comparison of binaural beamforming and MWF-based noise reduction algorithms for hearing aids
Noise reduction algorithms in hearing aids are crucial to improve speech understanding in background noise for hearing-impaired persons. For binaural hearing aids multi-microphone algorithms, exploiting signals from both the left and the right hearing aid, are considered to be promising techniques for noise reduction, because in addition to spectral information spatial sound information can be ...
متن کاملRate-Constrained Beamforming in Binaural Hearing Aids
Recently, hearing aid systems where the left and right ear devices collaborate with one another have received much attention. Apart from supporting natural binaural hearing, such systems hold great potential for improving the intelligibility of speech in the presence of noise through beamforming algorithms. Binaural beamforming for hearing aids requires an exchange of microphone signals between...

متن کاملNeural networks for speech separation for binaural hearing aids
This paper deals with the use of neural networks for separating speech from other noisy sources in binaural hearing aids. In sound separation systems implemented in binaural hearing aids, the right and left hearing aids need to transmit to each other some parameters involved in the speech separation algorithm. The problem is that this transmission reduces the battery life, which is one of the m...
