Over Time

The purpose of this investigation was to prospectively examine performance on the pure-tone air-conduction threshold, speech-recognition threshold, and suprathreshold word-recognition tests over time in 21 monaurally aided (experimental group) and 28 unaided adults (control group) with asymmetric, sensorineural hearing impairment.The results revealed significant declines on the mean suprathreshold word-recognition scores over time at one and two years post-baseline for the worse ears of the control participants; no declines occurred in the worse ears of the experimental participants or in the better ears of either group. A slight, significant increase in the pure-tone average occurred for the better ears of both groups. The findings are consistent with the presence of an auditory deprivation effect on suprathreshold word-recognition ability in the control group, suggesting that lack of amplification leads to decline in word-recognition performance over time in the worse ears of adults with asymmetric sensorineural hearing impairment.

Masking Level Difference

The purpose of this study was to determine if performances on a 500 Hz MLD task and a word-recognition task in multitalker babble covaried or varied independently for listeners with normal hearing and for listeners with hearing loss. Young listeners with normal hearing (n = 25) and older listeners (25 per decade from 40–80 years, n = 125) with sensorineural hearing loss were studied. Thresholds at 500 and 1000 Hz were ≤30 dB HL and ≤40 dB HL, respectively, with thresholds above 1000 Hz <100 dB HL. There was no systematic relationship between the 500 Hz MLD and word-recognition performance in multitalker babble. Higher SoNo and SπNo; thresholds were observed for the older listeners, but the MLDs were the same for all groups. Word recognition in babble in terms of signal-to-babble ratio was on average 6.5 (40- to 49-year-old group) to 10.8 dB (80- to 89-year-old group) poorer for the older listeners with hearing loss. Neither pure-tone thresholds nor word-recognition abilities in quiet accurately predicted word-recognition performance in multitalker babble.

Estudio De Caso

A case study of a child (KB) who demonstrated binaural interference is reported. KB wore unilateral amplification from 1.6 to 4.6 years of age, at which time word-recognition scores under phones were markedly asymmetric, reflecting significantly better performance for the aided ear than the unaided ear, despite similar unaided pure-tone sensitivity. Suspecting the asymmetry in word-recognition performance might be the result of auditory deprivation, bilateral amplification was prescribed at 4.6 years of age. Three months later, adverse changes in the child's behavior were reported. At 5.3 years, significant interaural asymmetry was noted in word-recognition scores under phones, in unilateral-aided word-recognition scores (90% vs. 36%), and in the bilateral-aided score (56%), supporting the presence of binaural interference. Se reporta el estudio de caso de un niño (KB) quién demostró un interferencia binaural. KB utilizó amplificación unilateral desde la edad de 1.6 a los 4.6 años, donde sus puntajes de reconocimiento de palabras bajo auriculares eran marcadamente asimétricos, reflejando un desempeño significativamente mejor en el oído amplificado que en el no amplificado, a pesar de una sensibilidad tonal sin amplificación similar para los dos oídos. Bajo la sospecha de que la asimetría en el reconocimiento de palabras se debiera a un deprivación auditiva, se prescribió una amplificación binaural a la edad de 4.6 años. Tres meses después, se reportaron cambios adversos en la conducta del niño. A los 5.3 años, se notó una significativa asimetría interauricular en los puntajes de reconocimiento de palabras con auriculares, en reconocimiento de palabras con amplificación unilateral (90% vs. 36%), y el puntaje bilateral con amplificación (56%), apoyando la presencia de una interferencia binaural.

The Relationship

The purpose of this experiment was to determine the relationship between psychometric functions for words presented in multitalker babble using a descending presentation level protocol and a random presentation level protocol. Forty veterans (mean = 63.5 years) with mild-to-moderate sensorineural hearing losses were enrolled. Seventy of the Northwestern University Auditory Test No. 6 words spoken by the VA female speaker were presented at seven signal-to-babble ratios from 24 to 0 dB (10 words/step). Although the random procedure required 69 sec longer to administer than the descending protocol, there was no significant difference between the results obtained with the two psychophysical methods. There was almost no relation between the perceived ability of the listeners to understand speech in background noise and their measured ability to understand speech in multitalker babble. Likewise, there was a tenuous relation between pure-tone thresholds and performance on the words in babble and between recognition performance in quiet and performance on the words in babble.
