Speech enhancement with multichannel Wiener filter techniques in multimicrophone binaural hearing aids.
This paper evaluates speech enhancement in binaural multimicrophone hearing aids by noise reduction algorithms based on the multichannel Wiener filter (MWF) and the MWF with partial noise estimate (MWF-N). Both algorithms are specifically developed to combine noise reduction with the preservation of binaural cues. Objective and perceptual evaluations were performed with different speech-in-mult...
متن کاملSpeech enhancement for multimicrophone binaural hearing aids aiming to preserve the spatial auditory scene
Modern binaural hearing aids utilize multimicrophone speech enhancement algorithms to enhance signals in terms of signal-to-noise ratio, but they may distort the interaural cues that allow the user to localize sources, in particular, suppressed interfering sources or background noise. In this paper, we present a novel algorithm that enhances the target signal while aiming to maintain the correc...
متن کاملBinaural hearing and future hearing-aids technology
Normal-hearing persons can make use of two ears in daily listening, and this binaural hearing offers a lot of advantages compared to monaural hearing. The mechanisms of binaural hearing are based on an analysis of interaural differences and monaural cues that are due to directional dependent filtering of the outer ears as described by HeadTransfer Functions. In order to support the binaural abi...
متن کاملEvaluation of adaptive multimicrophone algorithms for hearing aids.
It appears that one of the most important factors limiting the usefulness of hearing aids is the high sensitivity of hearing aid users to interfering sounds. In this work, the possibility of utilizing computing power that could be packaged into a unit the size of a hearing aid in order to cancel out noises before they reach the ear was investigated. Algorithms for combining the outputs of a num...
متن کاملMultimicrophone adaptive beamforming for interference reduction in hearing aids.
To reduce interference in monaural hearing aids from sound sources that are spatially separated from a target source, we are investigating methods for combining information from multiple microphones. In this paper, we describe an adaptive beamforming method that functions to preserve target signals arriving from straight-ahead of a microphone array while minimizing output power from off-axis in...
