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)

Auditory filter widths for six groups of subjects, adults and children, were tested with fixed signal level (psychophysical tuning curve procedure) and fixed masker (notched noise procedure). Found that auditory filter widths from ages six to adult were not significantly different, and auditory deficits that appear as a function of age likely…

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)

This study aimed to (a) investigate the effect of using a hearing aid in conjunction with a cochlear implant in opposite ears on speech perception in quiet and in noise, (b) identify the speech information obtained from a hearing aid that is additive to the information obtained from a cochlear implant, and (c) explore the relationship between…

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)

The ability of the sensitivity prediction from acoustic reflex (SPAR) technique to estimate hearing loss in 32 trainable mentally retarded Ss (adults and young adults with normal to profound hearing loss) was investigated by comparing measured pure-tone thresholds determined through tangible-reinforcement operant-conditioning audiometry with…

The purpose of this investigation was to document performance of participants wearing a cochlear implant and hearing aid in opposite ears on speech-perception and localization tests. Twelve individuals who wore a cochlear implant and a hearing aid on contralateral ears were tested on their abilities to understand words in quiet and sentences in…

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…

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…

A tracking procedure (lipreading of word groups that are repeated by a hearing-impaired listener), emphasizing practical coping strategies and practice in responding to cues in connected speech, was utilized with one deaf adult subject. Tracking scores before and after training illustrate the value of the procedure for evaluation and training.…
