Abstract Models of the human auditory periphery range from very basic functional
descriptions of auditory filtering to detailed computational models of cochlear mechanics …

Alterations of the speech signal, including additive noise and nonlinear distortion, can
reduce speech intelligibility and quality. Hearing aids present an especially complicated …

This paper presents a new feature extraction algorithm called power normalized Cepstral
coefficients (PNCC) that is motivated by auditory processing. Major new features of PNCC …

Abstract Peterson and Heil [Hear. Res., In Press] have argued that the statistics of
spontaneous spiking in auditory nerve fibers (ANFs) can be best explained by a model with …

Perception is thought to be shaped by the environments for which organisms are optimized.
These influences are difficult to test in biological organisms but may be revealed by machine …

This paper presents an improved index for predicting speech quality. The Hearing-Aid
Speech Quality Index (HASQI) version 2 is based on a model of the auditory periphery that …

A phenomenological model with time-varying excitation and inhibition was developed to
study possible neural mechanisms underlying changes in the representation of temporal …

A system and method for processing an acoustic input signal and providing at least one
output acoustic signal to a user of a hearing-aid system. The hearing-aid system includes …

The proposed hearing-aid speech quality index accurately predicts speech quality ratings
for hearing-impaired and normal-hearing listeners who were judging the quality of sound …

Acoustic trauma degrades the auditory nerve's tonotopic representation of acoustic stimuli.
Recent physiological studies have quantified the degradation in responses to the …
