The monosyllabic word discrimination of normal and hearing-impaired children was evaluated in situations selected to simulate acoustical conditions in current educational environments. All listeners were tested in a high-fidelity (loudspeaker-aided) condition under 12 combinations of reverberation and noise. Hearing-impaired subjects were also evaluated in the same 12 conditions while listening through a monaural hearing aid. Performance of the normal-hearing group was superior to the hearing-impaired listeners in all environments. Results suggest that classroom acoustics should be considered a critical variable in the educational achievement of children.

A picture identification test for measuring speech discrimination ability in hearing-impaired children was developed in two phases. In the first phase the word stimuli were evaluated to determine whether they were within the recognition vocabulary of the children and whether the pictorial representations of the words were adequate. Before the second phase, the test was revised to consist of 25 plates with 6 pictures on each plate, with only 4 of the pictures on each plate used as test stimuli. These 4 lists were given to 61 hearing-impaired children on two separate occasions. The results indicate reliability coefficients in excess of 0.87 for all four lists, with mean differences of less than 3% and correlation coefficients between lists greater than 0.84. The test appears to be a potentially valuable clinical tool in pediatric audiology. We call it the Word Intelligibility by Picture Identification test (WIPI).

This study attempted to maximize environmental language learning for four hearing-impaired children. The children's mothers were systematically trained to present specific language symbols to their children at home. An increase in meaningful use of these words was observed during therapy sessions. In addition, as the mothers began to generalize the language exposure strategies, an increase was observed in the children's use of words not specifically identified by the clinician as targets.

A commercial noise dose meter was used to estimate the equivalent noise dose received through high-gain hearing aids worn in a school for deaf children. There were no significant differences among nominal SSPL settings and all SSPL settings produced very high equivalent noise doses, although these are within the parameters of previous projections.

This paper presents the procedures developed and used in the individual treatment programs for a group of preschool, postrubella, hearing-impaired children. A case study illustrates the systematic fashion in which the clinician plans programs for each child on the basis of the child’s progress at any given time during the program. The clinician’s decisions are discussed relevant to (1) the choice of a mode(s) for the child and the teacher, (2) the basis for selecting specific target behaviors, (3) the progress of each program, and (4) the implications for future programming.

Listening, a significant dimension of the behavior of hearing-impaired children, may be measured directly by recording childrens' responses to obtain audio narrations programmed via a conjugate reinforcement system. Twelve hearing-impaired, school-aged children responded in varying ways to the opportunity to listen. Direct and continuous measurement of listening has relevance for evaluation of remediation methods and for discovery of variables potentially related to listening.

The identification of consonants in a/-C-/a/nonsense syllables, using a fourteen-alternative forced-choice procedure, was examined in 4 profoundly hearing-impaired children under five conditions: audition alone using hearing aids in free-field (A),vision alone (V), auditory-visual using hearing aids in free-field (AV1), auditory-visual with linear amplification (AV2), and auditory-visual with syllabic compression (AV3). In the AV2 and AV3 conditions, acoustic signals were binaurally presented by magnetic or acoustic coupling to the subjects' hearing aids. The syllabic compressor had a compression ratio of 10:1, and attack and release times were 1.2 ms and 60 ms. The confusion matrices were subjected to two analysis methods: hierarchical clustering and information transmission analysis using articulatory features. The same general conclusions were drawn on the basis of results obtained from either analysis method. The results indicated better performance in the V condition than in the A condition. In the three AV conditions, the subjects predominately combined the acoustic parameter of voicing with the visual signal. No consistent differences were recorded across the three AV conditions. Syllabic compression did not, therefore, appear to have a significant influence on AV perception for these children. A high degree of subject variability was recorded for the A and three AV conditions, but not for the V condition.

This study examines whether observers reliably categorize selected speech production behaviors in hearing-impaired children. A group of experienced speech-language pathologists was trained to score the elicited imitations of 5 profoundly and 5 severely hearing-impaired subjects using the Phonetic Level Evaluation (Ling, 1976). Interrater reliability was calculated using intraclass correlation coefficients. Overall, the magnitude of the coefficients was found to be considerably below what would be accepted in published behavioral research. Failure to obtain acceptably high levels of reliability suggests that the Phonetic Level Evaluation may not yet be an accurate and objective speech assessment measure for hearing-impaired children.
