The study examined the test-retest reliability in unaided and aided sound-field thresholds and the functional gain values derived from these measurements in 24 hearing-impaired adults. Test-retest standard deviations were slightly larger for functional gain than for unaided thresholds. (Author/DB)

A descending version of K. Hattler's Lengthened Off-Time (LOT) Bekesy test was administered to 24 hearing-impaired adults and 30 normal-hearing adults. The Descending LOT test substantially increased screening sensitivity relative to LOT test identifications, because of larger intertrace gaps. (Author/JDD)

This study examined developmental effects in auditory perception of word-final /s/ in inflectional morpheme contexts as a function of high-frequency (HF) bandwidth with normal hearing 5-, 7-, 10-year-olds and adults. The higher detection thresholds and larger clarity rating variances for the youngest participants support the use of extended…

Frequency difference limens (DLFs) for pure tones were obtained over a wide range of frequencies and levels from 7 normal-hearing subjects and 16 ears of 12 listeners with sensorineural hearing losses. Results indicated that it is reasonable to use data from normal listeners' DLFs to evaluate DLFs from hearing-impaired listeners. (Author/JDD)

Evaluates the discrimination of signal and silence duration in six-month-old infants, children aged 5 1/2 years, and adults. Results show that infants discriminated duration changes of 20 milliseconds or greater, children discriminated 15 milliseconds, and adults as few as 10 ms. Findings are consistent with other research in revealing age-related…

Temporal envelope and spectral cue resolution were evaluated simultaneously in seven adults with severe/profound hearing impairments. Results revealed that the Auditory Numbers Test (ANT) is differentially sensitive to responses based upon gross temporal envelope and spectral cues in the speech signal. The ANT is endorsed as a screening tool for…

This study examined the influence of stimulus context and audibility on sentence recognition in 60 normal-hearing children, 24 hearing-impaired children, and 20 normal-hearing adults. For both semantically correct and semantically anomalous sentences, there was a systematic age-related shift in the performance-intensity functions. Data from the…

A model and a technique developed by Wing and Kristofferson (1973) decomposes variance of timing into that putatively due to a central timekeeper (a clock) and that due to implementation of movement through the motor system. A patient with unilateral cerebellar damage, when attempting to tap out a regular series of intervals, showed a large…

This experiment sought to define a confidence limit for maximum word-recognition scores obtained from 212 young and elderly adults with confirmed cochlear hearing loss. A 95% confidence limit was found and supported through analysis, although it is suggested that, in some cases, word recognition should be measured at additional levels to obtain…

Two studies with 20 hearing-impaired and 10 normal-hearing adults found that the Hearing Performance Inventory-Revised was insensitive to differences in hearing-impaired listeners' consonant-recognition ability, whereas the Nonsense Syllable Test was sensitive to differences in overall consonant-recognition ability for normal-hearing and…
