A Simulation Study on Binaural Dereverberation and Noise Reduction based on Diffuse Power Spectral Density Estimators
Enhancement techniques in binaural hearing aids are crucial to improve speech understanding for hearing impaired persons in reverberation and noise. Since reverberation and noise can be commonly modeled as diffuse sound fields, many state-of-theart techniques require an estimate of the diffuse power spectral density (PSD). In this paper we evaluate the performance of binaural dereverberation an...
متن کاملCombined Noise Reduction and Coherence Reshaping for Binaural 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, algorithms that exploit the microphone 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 information can be exploit...
متن کاملRate-constrained binaural MWF-based noise reduction algorithms
In a binaural hearing aid system, output signals for the left and the right ear are generated by exchanging information between the two hearing aids. A significant noise reduction can be achieved using the binaural multi-channel Wiener filter (MWF), which requires all microphone signals from both hearing aids. However, the limited bandwidth of the binaural link typically does not allow to trans...
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 کاملMulti-channel algorithms for wind noise reduction and signal compensation in binaural hearing aids
This paper contains a new approach for wind noise reduction in binaural hearing aids. This approach combines the ”single-channel low frequency reduction” algorithm [1] and the ”two-channel correlation detector” [2] with a multi-channel binaural hearing aid to compensate the desired signal. The algorithm benefits from the fact that if wind comes from one side, the wind noise mostly occurs in the...
