Measurement of phonemic degradation in sensorineural hearing loss using a computational model of the auditory periphery
A computational model of the auditory periphery enables faster investigation of new signal processing algorithms for hearing aids. This paper presents a study of the degradation of auditory nerve (AN) responses at a phonetic level for a range of sensorineural hearing losses. The AN model of Zilany & Bruce was used to compute responses to a diverse set of phoneme rich sentences from the TIMIT da...
متن کاملAnalysis of spatiotemporal pattern correction using a computational model of the auditory periphery.
OBJECTIVES The purpose of this study was to determine the cause of poor experimental performance of a spatiotemporal pattern correction (SPC) scheme that has been proposed as a hearing aid algorithm and to determine contexts in which it may provide benefit. The SPC scheme is intended to compensate for altered phase response and group delay differences in the auditory nerve spiking patterns in i...
متن کاملInsights into optimal phonemic compression from a computational model of the auditory periphery
Phonemic compression schemes for hearing aids have thus far been developed and evaluated based on perceptual criteria such as speech intelligibility, sound comfort, and loudness equalization. Finding compression parameters that optimize all of these perceptual metrics has proved difficult. The goal of this study was to find optimal single-band gain adjustments based on the response of auditory-...
متن کاملComputational modeling of the human auditory periphery: Auditory-nerve responses, evoked potentials and hearing loss
Models of the human auditory periphery range from very basic functional descriptions of auditory filtering to detailed computational models of cochlear mechanics, inner-hair cell (IHC), auditory-nerve (AN) and brainstem signal processing. It is challenging to include detailed physiological descriptions of cellular components into human auditory models because single-cell data stems from invasiv...
متن کاملPeriphear : a nonlinear active model of the auditory periphery
This paper describes a phenomenological model of the auditory periphery which consists of a bank of nonlinear time-varying parallel lters. Realistic lter shapes are obtained with the all-pole gammatone lter (APGF) which provides both a good approximation of the far more complex wave-propagation or cochlear mechanics models and a very simple implementation. The model also includes an active, dis...
