    Research in auditory training
    Blamey, Peter J. ; Alcantara, Joseph I. (Academy of Rehabilitative Audiology, 1994)
    Speech perception and communication can improve as a result of experience, and auditory training is one way of providing experiences that may be beneficial. One of the most important factors influencing the effectiveness of auditory training is the amount of experience the client already has. Other factors include the severity of the hearing loss, the sensory device used, the environment, personal qualities of the client and clinician, the type of training, and the type of evaluation used. Despite a long history of clinical practice, the effects of these factors have been investigated in few controlled studies. Even in special cases where training has an obvious role, such as adults using cochlear implants, there has been little objective comparison of alternative training methods. One reason for this is the difficulty of carrying out definitive experiments that measure changes in performance over time in the presence of many confounding variables. These variables may also help to explain the apparently contradictory results that can be found in the literature on auditory training and in the diverse points of view expressed by practicing clinicians. Issues and methods appropriate for research in auditory training among adult clients are discussed with reference to the needs of modem clinical practice.

    Speech perception for adults using cochlear implants
    Dowell, Richard C. (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.
