A report which outlines the operation and some applications of an automatic audiovisual system for the assessment of a subject's phonemic discrimination ability based on a two-alternative forced-choice response situation. (Author)

Forward-masked psychophysical tuning curves were obtained at multiple probe levels from 26 normal-hearing listeners and 24 ears of 21 hearing-impaired listeners with cochlear hearing loss. Results indicated that some cochlear hearing losses influence the sharp tuning capabilities usually associated with outer hair cell function. (Author/JDD)

The paper describes the unexpected finding of evoked otoacoustic emissions from one ear of a subject with severe-to-profound bilateral sensorineural hearing loss. It is suggested that the subject may have a group of surviving outer hair cells in some regions of the left cochlea with corresponding inner hair cell or neural damage. (Author/DB)

The application of the Articulation Index (AI) model to the fitting of linear amplification was evaluated for 12 subjects with sensorineural hearing loss. For all subjects, the relationship between percent-correct scores on a nonsense syllable test and AIs was monotonic, indicating that AI was effective for comparing conditions typical of those…

The study employed measures of frequency resolution obtained from individual subjects (two normal and three with sensorineural hearing loss) to predict each subject's vowel recognition performance. A relation between impairments of frequency resolution and vowel recognition was found. The described model may be useful in predicting vowel…

Examples of pattern cues that are available to profoundly hearing-impaired children are presented through an optical analog, and the usefulness of these cues is shown with regard to vowel and consonant identification, word stress-pattern perception, and distinction among sentences that differ in number of syllables, pattern, intensity, or rate.…

Simultaneous recordings of auditory brainstem and middle latency responses were obtained in both vertex-ipsilateral and vertex-contralateral derivations in 22 children, ages 8-12. For specific recording conditions, the latencies of middle latency responses differ significantly between children with and without learning disabilities, offering…

Sensitivity and specificity of static acoustic admittance (SAA) and tympanometric width (TW) were assessed for 116 pediatric patients. A statistically significant change in SAA was observed in immediate repeat measures. No significant change across the two sequential measures was observed for TW, peak pressure, or the estimate of ear canal volume.…

Behavioral studies of listening in children with both normal and exceptional hearing are presented. The conjugate of assessing listening is discussed. This method provides a continuous record of ongoing behavior allowing for observation of moment-to-moment changes in listening. It determines how sustained, how strong, and how continuous a child's…

The article reviews problems and principles of impedance audiometry and discusses its value to school speech and language clinicians. (CL)

Puretone auditory assessment of 21 adults with severe to profound mental retardation indicated that a bivariate plotting procedure of predicting hearing sensitivity from the acoustic reflexes should be included in an audiological test battery for this population. (CL)

Proposed is a study to evaluate the auditory systems of learning disabled (LD) students with a new audiological, diagnostic, stimulus apparatus which is capable of objectively measuring the interaction of the binaural aspects of hearing. The author points out problems with LD definitions that exclude neurological disorders. The detection of…

Measures of transient evoked otoacoustic emission (TEOAE) reproducibility were obtained for 506 ears of 260 children and young adults. Findings suggest that TEOAEs provide useful information in routine clinical practice and may be employed to screen for the presence of hearing loss in children and young adults. (DB)

The study evaluated use of the Modified Power Law to predict permanent threshold shift (PTS) resulting from noise exposure in eight children with severe sensorineural hearing loss attributed to overamplification by hearing aids. The PTS tended to be flat across frequency with its course similar to PTS in persons with normal hearing exposed to…
