Andrew Hines, Naomi Harte, Measurement of phonemic degradation in sensorineural hearing loss using a computational model of the auditory periphery, IET Irish Signals and Systems Conference ISSC 2009, UCD, June 1011, 2009, 1-6
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 database. The
characteristics of both the average discharge rate and spike timing of the responses are
discussed. The experiments demonstrate that the model responses are consistent with
respect to impairment and inaudible thresholds.
