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.

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.

Aided threshold improvement obtained by 12 hearing-impaired children was compared to the acoustic gain of their hearing aids using both the traditional 2-cc coupler and a variable volume coupler designed to approximate real ear volume in children. Results indicated that acoustic gain determined in the 2-cc coupler underestimated aided threshold improvement by approximately 8.7 dB. Use of the variable volume coupler to determine acoustic gain, however, adequately predicted aided improvement at comfort setting. Use of the variable volume coupler in hearing-aid fittings for children is discussed with special emphasis on preventing over-amplification.

Background: Hearing impairment is a factor that directly compromises the individual’s language which can affect emotional and academic defects by delayed development of communicative ability. This can vary according to the type and degree of hearing loss. Speech therapy intervention is important, along with the use of sound amplification devices, so that the child may have a chance to develop speech, consequently learning and re-habilitation to the society. Aims of the present study was performed to assess the effectiveness of early intervention of speech and language therapy after use of hearing aids to hearing impaired children on their syntactic and lexical development.Methods: This quasi-experimental study conducted on 100 children having different degree of hearing loss at department of Neurology and department of ENT, King George’s Medical University, Lucknow, Uttar Pradesh. After collecting socio-demographic data of subjects by observation, completion of questionnaires, and speech recording by audiologist; Speech and language therapy provide by audiologist for six month after providing hearing aids and improvement in their syntactic and lexical development recorded.Results: There is significant improvement in verbal response from 14% before therapy to 81% after therapy and non-verbal response before therapy was 86% and after therapy was 19%. Before giving speech and language therapy to subjects pointing score was 24%, sign language was 10% and words response was 0% which increases after therapy were 1%, 2% and 39% respectively. Early identified/intervened hearing-impaired children had a notable positive difference in all assessed lingual gains.Conclusions: This is study results definitely point to positive effects of intensive and continuous application of speech and language therapy to syntactic and lexical development of hearing impaired children.
