Many competing noises in real environments are modulated or fluctuating in level. Listeners with normal hearing are able to take advantage of temporal gaps in fluctuating maskers. Listeners with sensorineural hearing loss show less benefit from modulated maskers. Cochlear implant users may be more adversely affected by modulated maskers because of their(More)

The discriminability of bilabial stop consonants differing in VOT (the Abramson-Lisker bilabial series) was measured in a same-different task, an oddity task, and a dual response, discrimination--identification task. Subjects showed excellent within-category discrimination in all three tasks after a moderate amount of training in a same-different task with(More)
This study investigates patterns of speech discrimination in profoundly hearing-impaired children who have received cochlear implants or tactile aids. The change/no change procedure was used to assess speech discrimination in these children. Three groups of subjects were tested: the first group used 3M/House single-channel cochlear implants; the second(More)
This article provides a review of the topic of treatment efficacy for children with hearing loss. Efficacy is related to a wide range of treatment goals in the areas of sensory and perceptual skill development, language development (regardless of communication modality), speech-production skill development, academic performance, and social-emotional growth.(More)
Simultaneous psychophysical tuning curves were obtained from normal-hearing and hearing-impaired listeners, using probe tones that were either at similar sound pressure levels or at similar sensation levels for the two types of listeners. Tuning curves from the hearing-impaired listeners were flat, erratic, broad, and/or inverted, depending upon the(More)
OBJECTIVE This experiment was designed to assess the integration of auditory and visual information for speech perception in older adults. The integration of place and voicing information was assessed across modalities using the McGurk effect. The following questions were addressed: 1) Are older adults as successful as younger adults at integrating auditory(More)
This study examined the variables that contribute to the large individual differences in the speech perception skills of children with the Nucleus multichannel cochlear implant. Sixty-one children were tested on four measures of speech perception: two tests of closed-set word recognition, one test of open-set recognition of phrases, and one open-set(More)
A comparative study of the speech-like vocalizations of a deaf infant and a group of 11 hearing infants was conducted in order to examine the role of auditory experience in the development of the phonological and metaphonological capacity. Results indicated that from 8 to 13 months of age, the deaf subject differed strikingly from hearing infants of(More)
The purpose of this investigation was to study the impact of hearing loss on phonatory, velopharyngeal, and articulatory functioning using a comprehensive physiological approach. Electroglottograph (EGG), nasal/oral air flow, and intraoral air pressure signals were recorded simultaneously from adults with impaired and normal hearing as they produced(More)
Suprasegmental and segmental speech perception tasks were administered to 8 patients with single-channel cochlear implants. Suprasegmental tasks included the recognition of syllable number, syllabic stress, and intonation. Segmental tasks included the recognition of vowels and consonants in three modalities: visual only, implant only, and visual + implant.(More)
