Auditory-model based assessment of the effects of hearing loss andhearing-aid compression on spectral and temporal resolution
free download

Most state-of-the-art hearing aids apply multi-channel dynamic-range compression (DRC). Such designs have the potential to emulate, at least to some degree, the processing that takes place in the healthy auditory system. One way to assess hearing-aid performance is

EVALUATION OF SOUND CLASSIFICATION USING MODIFIED CLASSIFIER AND SPEECH ENHANCEMENT USING ICA ALGORITHM FOR HEARING AID
free download

Abstract Hearing aid users are exposed to diversified vocal scenarios. The necessity for sound classification algorithms becomes a vital factor to yield good listening experience. In this work, an approach is proposed to improve the speech quality in the hearing aids

Effect of Multichannel and Channels Free Hearing Aid Signal Processing On Phoneme Recognition in Quiet and Noise.
free download

ABSTRACT Introduction: Older adults with sensorineural hearing loss (SNHL) find it difficult to understand speech especially, in noise. Hearing aid is one among the rehabilitative option available to them. Even with advent in hearing aid technology, adequate benefit for

Probabilistic 2D localization of sound sources using a multichannel bilateralhearing aid
free download

Modern hearing aids typically use multiple microphones, which allow for advanced spatial filtering techniques (eg beamforming) to be used. To be effective, these algorithms need to be steered intelligently, such that the source of interest is enhanced whereas interfering
