Investigation of the Hearing Test Results for the Hearing Impaired Children Followed up More than 3 Years

Abstract

From the results of hearing test for the hearing impaired children whom we have followed up more than 3 years, we discussed about its reliability and the shift of hearing threshold.
Test results showed that hearing test of the children above 3 years was considerably reliable. The fluctuation of hearing loss due to hearing aid usage was observed in some cases of them who had been using hearing aids extending over long period, but this type of threshold shift was reversible to some extent in spite of sensorineural hearing loss. Consequently this seems to be preventible to some extent through either alternative or temporalily interrupted usage of hearing aid.
