This study examined the timing suitable for transplanting Artificial cochlear by comparing
two groups\' ability differences of speech perception after we analysed as an object of this
study both 15 children transplanted artificial cochlear under six years of age and 15 children
transplanted artificial cochlear aged six and above.
This study analysed hearing situations of both Auditory Only(AO) and Auditory
Visual(AV) based on one syllable and two syllable examination of speech perception without
any examples suggested by Kim, Soo-Jin(1988), and examined independent sampling t by using
SPSS 12.0. As a result, there were meaningful differences of speech perception between
children\'s groups transplanted at the age of 6 more or less in the situations of AO and AV
without any examples.
There were individual differences, but generally children transplanted under more or less
six years of age had a little more performance ability of speech perception than children aged
six and above.
It was shown that, by reconsidering the operation of artificial cochlear which has been
thoughtlessly performed today, this study would be a basic material of study to examine efficient
rehabilitation methods of hearing-impaired children through carefully considering the
suited timing for transplanting artificial cochlear.
