The problems associated with earmoulds currently used by hearing-impaired persons, particularly children, are outlined. A new type of earmould which combines high efficiency with minimal feedback is described and evaluated.
This report of work in progress describes the GMC project, an investigation of the language and development of hearing-impaired children born within the Greater Manchester area in the years 1977-1980 inclusive. The aim of the language section of the project is to describe the acquisition and development of spoken language by a complete population of children with sensori-neural hearing loss. Comprehensive audiological, aetiological and sociological background information is kept as well as the results of standardized psychological and language tests and videotaped samples of spontaneous language. Details of objectives and methodology are given in the report.
152 conversational ability which goes beyond a descriptive analysis of wellformed exchanges to an investigation of how conversations are initiated and sustained. One way of tackling this issue is to study samples of conversational incompetence. The present paper presents data from a ten-year-old boy in a special language school, whose conversations have been described as 'bizarre'. On the basis of these samples, a model of conversation is constructed which includes an interactional component, accounting for the well-formedness of reciprocally related utterances, and a transactional component, which accounts for the structuring and presentation of communicative information.
The problems involved in producing efficient ear moulds for children have been examined. It is suggested that materials do exist such that the general quality of ear moulds could be significantly improved. However, manufacturing techniques require modification and a more comprehensive training programme for ear mould technicians is urgently required.
