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
