Multichannel cochlear implantation has been a viable option for providing

access to sound for children with bilateral profound sensorineural hearing loss

for over twenty years. A cochlear implant (CI) is a surgically implanted

prosthesis which bypasses damaged structural or functional abnormalities of the

cochlea to provide electrical stimulation of remaining neural elements in the

cochlea and auditory nerve. This electrical stimulation leads to a percept of

sound. However, hearing through a CI is highly compromised in terms of

temporal and frequency resolution, as well as dynamic range of the input signal

(Wilson, 1997). Despite these compromises, there is considerable evidence that

children can use this signal to develop speech, oral language, and reading skills

(Geers, 2003; Spencer, Barker, & Tomblin, 2003; Svirsky, Robbins, Kirk, Pisoni,

& Miyamoto, 2000).
