    The history of cochlear implant use by adults and children with profound hearing loss although relatively short (20 some years), has been characterised by continual technological innovations which have enhanced the performance, packaging, and clinical use of these devices. In particular, the development of the Nucleus multiple channel cochlear implant has included a series of speech processing hardware and speech processing strategy, implemented by Cochlear Limited, and based on research findings that have resulted in an increase in mean speech perception benefits for adults and children.

    Steady state evoked potentials (SSEPs): An objective measure of residual hearing in young cochlear imlpant candidates
    Rance, G. ; Rickards, F. W. ; Dowell, R. C. ; Cohen, L. T. ; Clark, Graeme M. ( 1993)
    The use of objective measures of residual hearing in young cochlear implant candidates has become more important as the minimum age of implantation has reduced. This paper examines the use of the steady-state evoked potential (SSEP) technique in the assessment of these children. SSEP thresholds were obtained using frequency specific stimuli at octave frequencies between 250llz and 4000Hz in ZS children with moderate to severe hearing losses. These levels, determined automatically by a computerized detection system were then compared with thresholds obtained behaviourally. Data was also collected from a group of 35 adult subjects with varying degrees of sensorineural hearing loss. Results indicate that the steady-state evoked potential procedure can provide accurate, frequency specific estimates of hearing thresholds in ears with even profound or total hearing losses.
