Subjective impressions of child cochlear-implant users: effects of conversational fluency, intelligibility, speech perception, and communication mode

This paper investigates the conversational fluency of young cochlear implant users. The study compares objective measures and subjective impressions of conversation fluency, relates how children’s communication skills influence both objective and subjective measures of conversational fluency, and compares the performance of children who use an oral mode with those who use a total communication mode in everyday conversation.

The development of the computerized version of the early speech perception test battery

This paper discusses the development of a computerized version of the CID Early Speech Perception Test.

Social-emotional adustment in deaf children: An investigation of the relationship between academic and speech perception abilities to social-emotional adjustment

This paper discusses the results of a study undertaken to determine if there is a relationship between psychological variables and cognitive or academic variables among hearing-impaired children.

The effects of hearing aid gain on speech perception and the articulation index

This paper discusses a study to determine if changes in aided articulation indices predict changes in aided speech perception ability.

The perception of vowels in hearing and hearing-impaired subjects

This paper examines the relationship between speech discrimination ability and vowel map accuracy and vowel map size.

Frequency responses of hearing aids and their effects on the speech perception of eight hard-of-hearing subjects

This dissertation examines the relationship between frequency response and word-discrimination performance of hearing-impaired persons. Three questions are addressed: does the restoration of the normal field-to-eardrum transfer function improve word discrimination; is the restoration of the normal shape of the audibility curve (uniform hearing level at all frequencies) beneficial to hearing-impaired listeners; and can speech discrimination be improved by an extension of the present narrow-band response in hearing aids.

Speech perception by the chinchilla: discrimination of /I/ and /A/ in various consonantal contexts

This paper discusses a study done with chinchillas and their ability to organize speech sounds into auditory concepts.

Dimensional tradeoffs in the perception of complex tone sequences

This paper reviews a study of four complex tones and sound perception among the tones.

The effect of talker age and gender on speech perception of pediatric cochlear implant users

Most clinically-employed speech materials for testing hearing impaired individuals are recordings made by adult male talkers. The author examined the possible effect of talker age and gender on the speech perception of children through the use of 1) two speech perception tests, each with four talker types (adult males, adult females, 10-12 year olds, 5-7 year olds), and 2) two groups of pediatric listeners: normal-hearing (NH) and cochlear implant users (CI).

Student musicians' perception of loudness and how it correlates to the measured level

The purpose of this project was to evaluate student musicians’ perception of loudness and see how it relates to the measured sound level when playing an instrument alone and when playing in an orchestra. Perhaps by examining this relationship, strategies can be developed to educate musicians on the risk of excessive noise exposure and hearing protection options.

Evaluation of auditory-visual speech perception in individuals diagnosed with dementia of the Alzheimer's type

Auditory-visual speech perception testing was completed using wordandconsonant-level stimuli in individuals with known degrees of dementia of theAlzheimer’s type. The correlations with the cognitive measures and the speechperception measures (A-only, V-only, AV, VE or AE) did not reveal significantrelationships.

The effect of talker age and gender on speech perception of pediatric hearing aid users

Even though pediatric hearing aid (HA) users listen most often to female talkers, clinically-used speech tests primarily consist of adult male talkers' speech. Potential effects of age and/or gender of the talker on speech perception of pediatric HA users were examined using two speech tests, hVd-vowel identification and CNC word recognition, and using speech materials spoken by four talker types (adult males, adult females, 10-12 year old girls, and 5-7 year old girls). For the nine pediatric HA users tested, word scores for the male talker's speech were higher than those for the female talkers, indicating that talker type can affect word recognition scores and that clinical tests may over-estimate everyday speech communication abilities of pediatric HA users.

A comparison of physical measurements of pure-tones, third-octave bands of noise and third-octave bands of speech to subjective judgments of audibility threshold, MCL and UCL for three normally hearing listeners

This study investigates the relation between physical measurements of pure-tones, third-octave bands of noise and third-octave bands of speech and subjective judgments of auditory threshold, most-comfortable listening level (MCL) and uncomfortable-listening level (UCL) for three normally hearing listeners.

A comparison of the performance of aphasoid and non-aphasoid children in learning to discriminate among auditory stimuli

This paper discusses auditory perception differences in aphasic and non-aphasic children

Patient perception of disability following acoustic (vestibular) schwannoma removal via gamma knife and microsurgical techniques

This study evaluates patient's short and long-term balance function after microsurgical tumor removal and gamma knife radiosurgery using an unvalidated qualitative questionnaire and the Dizziness Handicap Inventory.
