Journal ArticleDOI
Correct tonotopic representation is necessary for complex pitch perception
TL;DR: It is found that human subjects displayed poor pitch perception for single tones and none of the subjects was able to extract the fundamental frequency from multiple low-frequency harmonics presented to high-frequency regions of the cochlea.
Journal ArticleDOI
Auditory and auditory-visual intelligibility of speech in fluctuating maskers for normal-hearing and hearing-impaired listeners.
TL;DR: Data suggest that HI listeners retain more of an ability to listen in the dips of a fluctuating masker than previously thought, and a modified version of the extended speech-intelligibility index that predicts a larger FMB at less favorable SNRs accounted for most of the FMB differences between listener groups and modalities.
Journal ArticleDOI
Pitch discrimination of diotic and dichotic tone complexes: Harmonic resolvability or harmonic number?
TL;DR: Results under diotic and dichotic conditions indicate that the auditory system, in performing f0 discrimination, is unable to utilize the additional peripherally resolved harmonics in the dichotic case, and suggest that harmonic number, regardless of peripheral resolvability, governs the transition between two different pitch percepts.
Journal ArticleDOI
The relationship between frequency selectivity and pitch discrimination: sensorineural hearing loss.
TL;DR: Evidence of a relationship between fo discrimination performance and frequency selectivity in listeners with SNHL is provided, supporting "spectral" and "spectro-temporal" theories of pitch perception that rely on sharp tuning in the auditory periphery to accurately extract fo information.
Journal ArticleDOI
Spectrotemporal modulation sensitivity as a predictor of speech intelligibility for hearing-impaired listeners.

TL;DR: Combining STM sensitivity estimates with audiometric threshold measures for individual HI listeners provided a more accurate prediction of speech intelligibility than audiometric measures alone, suggesting a significant likelihood of success for an STM-based model of speechelligibility for HI listeners.
