Abstract:
Miyamoto, Osberger, Todd, Robbins, Karasek et al. (1994) compared the speech perception skills of children with profound prelingual deafness who had received the Nucleus multichannel cochlear implant (CI) to those who were not implanted and used conventional hearing aids (HA). The CI users were tested over time and the HA users were tested at a single point in time. They found that the CI users improved their scores on speech perception tasks a great deal over time. After about 2.5 years of device use, the CI users were performing better than the average performance from a group of Silver (PTA=104 dB HL) HA users on all tests, and their scores were approaching the average scores from a group of Gold (PTA=94 dB HL) HA users except on tests of open-set sentence recognition.
