Efficient Speech Dereverberation for Binaural Hearing Aids
An efficient two-stage algorithm for binaural cue preserving speech dereverberation by spectral weighting is presented. The first stage reduces late reverberant speech components where the second stage aims at a suppression of non-coherent early and remaining late reverberant speech components. The proposed system is based on the binaural speech dereverberation algorithm of Jeub et al. [3]. In ...
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 کاملRole of binaural hearing in speech intelligibility and spatial release from masking using vocoded speech.
A cochlear implant vocoder was used to evaluate relative contributions of spectral and binaural temporal fine-structure cues to speech intelligibility. In Study I, stimuli were vocoded, and then convolved through head related transfer functions (HRTFs) to remove speech temporal fine structure but preserve the binaural temporal fine-structure cues. In Study II, the order of processing was revers...
متن کاملBinaural hearing, atresia, and the masking dilemma.
A masking dilemma occurs when energy from a non-test ear crosses over the head to a test ear. In cases of bilateral atresia, obtaining thresholds on the poorer ear is problematic. Near threshold, however, sufficient ear-bone isolation exists to test with validity but not so much above threshold, even for the ultra-high (> 10 kHz) frequencies. This aspect of the bone audiogram should not be over...
متن کاملacoustic feedback suppression in binaural hearing aids
background and aim : the hearing loss and acoustic feedback signal in the binaural hearing aids may annoy users, make speech reorganization difficult, and affect the sound quality. this paper presents a new method for acoustic feedback suppression in binaural hearing aids, based on the combination of binaural information and blind source separation. this method can enhance sound from the specif...
