Speech processing strategy preferences among 55 European CLARION cochlear implant users.

This multicentre study investigates the preference and performance of a group of 55 adult CLARION cochlear implant users with the choice of simultaneous analogue stimulation (SAS) and continuous interleaved sampler (CIS) strategies during the first 3 months of implant use. Subjects were programmed with both strategies and instructed to use each of the two strategies in daily life to ascertain preference. Subjects were tested in both strategies with open-set sentence materials, auditory alone, at 2, 6 and 12 weeks after the initial programming session. Questionnaires were completed with preference ratings being recorded for the two strategies: 25% of subjects preferred SAS and 75% CIS. Subjects performed better in their strategy of choice. Preferences were set very early on in the process and did not change. Factors influencing preference are discussed. Offering the choice of fundamentally different strategies improves both individual and group performance.

Requirements of structure and resource for an adequate audiology service in the post-Griffiths Health Service.

Planning the development of services in audiology has been hampered by lack of an explicit set of recommendations concerning the range of services to be offered and their detailed procedural content. We provide this and bracket each service component with its resource requirements, indicating roughly what it should cost to introduce or appropriately deliver each component. We provide such a list, distinguishing between routine services requiring to be organised at health district level and those more specialised (low-patient-volume) services that are more appropriately centralised. This framework encourages explicit decisions as to what services are made available at each site, in the light of economic and other factors, and allows of contracting between districts to meet the needs of the population, rather than assuming a fixed model for a district service.

Difficulties experienced by hearing-aid candidates and hearing-aid users.

Responses to an open-ended questionnaire were obtained from 250 hearing-aid candidates who had never worn a hearing aid and from 250 experienced hearing-aid users. The questionnaire stated 'Please make a list of the difficulties which you have as a result of your hearing loss.' The responses were divided into six major categories. The hearing-aid candidates reported more problems than the experienced users in the categories of (a) understanding speech where speechreading would normally be used (92% versus 81%), and (b) understanding speech where speechreading would normally not be used (51% versus 43%). A similar number of respondents in both groups reported problems in the categories of (c) personal difficulties (11%), (d) audiological or medical difficulties (18%), and (e) difficulties associated with environmental sounds (34%). Thirty-five per cent of the hearing-aid users reported (f) difficulties associated with their hearing aids. The most frequently reported specific difficulty in both groups was watching television (47% of the candidates and 37% of the users). Twenty-one per cent in each group reported difficulty conversing on the telephone.
