Ninetieth percentile cutoffs for acoustic reflex thresholds (ART) were determined for a sample of 1,374 adult subjects with normal hearing and sensorineural loss of cochlear origin. It was found that 12.2 percent had one ear ART elevated above the ninetieth percentile, but only 5.6 percent had more than one elevated ART. (DB)

Purpose: The goal of this study was to determine the impact of age, gender, and race on the prevalence and severity of hearing loss in elder adults, aged 72-96 years, after accounting for income, education, smoking, and clinical and subclinical cardiovascular disease. Methods: Air-conduction thresholds for standard and extended high-frequency…

Purpose: To investigate the effects of talker variability on vowel recognition by cochlear implant (CI) users and by normal-hearing (NH) participants listening to 4-channel acoustic CI simulations. Method: CI users were tested with their clinically assigned speech processors. For NH participants, 3 CI processors were simulated, using different…

Examined was the performance of 18 normal and 20 learning disabled (LD) 8- to 9-year-old children on two competitive measures of auditory discrimination. Ss were administered the Wepman Auditory Discrimination Test (1974) and the Goldman, Fristoe, Woodcock Test of Auditory Discrimination (1970). Results suggested that little correlation exists…

Text and graphs describe the Dynamic Range Configuration audiogram developed at the Central Institute for the Deaf in St. Louis, Missouri. The audiogram displays the portion of the average speech spectrum audible to the child, with and without amplification, and can be effective in counseling parents and planning appropriate amplification.…

A bone conduction hearing screening test using frontal bone oscillator placement was compared with pure-tone air-conduction screening and impedance audiometry with 114 preschoolers. Unoccluded frontal bone conduction testing produced screening results not significantly different from results obtained by impedance audiometry. (CL)!

This article is a first step toward the construction of random measurement theories. A random version of additive conjoint measurement is proposed and developed in detail. (Editor)

Details are presented of a case of acoustic neuroma in which there was a discrepancy between Bekesy sweep-frequency results and those of fixed frequency traces and a tone-decay test. (Author)

The Bekesy and Rosenberg procedures were used to investigate whether tone decay varies systematically as a function of the initial hearing threshold level of the test tone in sensorineural loss. Tone decay tended to increase with increased hearing threshold level for both tests at all three frequencies used. (Author/KW)

Analyzes a method of detecting changes in a particular frequency band by evaluating the overall shape or profile of the auditory signal spectrum. Claims that profile analysis is different from intensity discrimination, and applies the new method to detecting noise sinusoid and to results obtained when signal frequency is uncertain.

The outcome of hearing screening using conventional pure tone behavioral testing was compared with the outcome employing measures of transient otoacoustic emissions (TEOAEs) in a preschool population under conditions typical of educational settings. Two hundred children ranging in age from 2 years 1 month to 5 years 10 months were screened. Nearly…

Purpose: To assess the Computerized Revised Token Test (CRTT) performance of individuals with normal hearing under several intensity conditions and under several spectral and temporal perturbation conditions. Method: Sixty normal-hearing listeners were randomly assigned to 1 of 3 groups. Group 1 provided performance-intensity information about…
