ItemSpeech perception for adults using cochlear implants(Whurr, 1994)A mere 16 years ago, the title of this chapter would have created considerable consternation in audiological circles. A high proportion of otologists and audiologists would have wondered, with good reason, about the potential content of such a chapter. In 1977, there were certainly cochlear implants in use with reported benefits, but reliable documentation of any useful speech perception under controlled conditions was difficult to find. The rapid development of cochlear prostheses since that time has led to thousands of profoundly hearing-impaired adults obtaining benefits for speech perception, and there is now no doubt regarding the efficacy of such devices. This chapter will provide a brief overview of this rapid improvement in the speech perception of adult cochlear implant users, consider some of the reasons for this improvement, and discuss some of the factors that may influence speech perception performance for the individual user.

ItemCochlear implants: historical perspectives(Whurr, 1995)These historical perspectives are seen from a personal point of view, and date back to the author's first involvement with cochlear implant research at the beginning of 1967. The perspectives are aimed at presenting the questions asked, the difficulties faced and the solutions achieved in the development of our multichannel cochlear prosthesis. Work in other centres is discussed when relevant, to set our research in context. Space does not permit a detailed presentation of our research or the contributions of others. It is hoped, however, that by presenting personal perspectives on the cut and thrust of human endeavour, and its interface with technology, a contribution will be made to the overall goal of understanding the origins of cochlear implants.
