Abstract: To profile the quality of sound in post - lingual Cochlear Implantees.20 random post - lingual Cochlear Implantees who were implanted at MERF - ISH (P) Ltd. were selected and participated in the study. The questionnaire was administered to the 20 participants who were native Tamil speakers and who were able to read Tamil were selected for the study. Adult Post - lingual CI users with minimum of 6 month of implant age were selected for the study. Participants were unilateral, bilateral Implantees. In relevance to experience, regular usage (minimum of 8 hours per day) of cochlear implant was considered. The translation of this questionnaire was done on the basis of guidelines given by World Health Organization (process of translation and adaptation of instruments, 2008) Forward translation, Expert panel back translation, Pre testing and cognitive interviewing Final version. Results showed that there was no correlation between the total HISQUI scores and age at implantation. Correspondingly in original HISQUI19 German - language validation study they found only a slight and not significant difference between the scores of subjects younger than 60 years at implantation and those older than 60 years, though a stratification was not done in the present study. Based on the results of this study we may conclude that the HISQUI19 Tamil version is a valid measure of self - perceived sound quality in everyday listening situations in adult CI users with post - lingual hearing loss. It is also a useful instrument for evaluating the subjective outcomes of cochlear implantation and helpful for improving rehabilitation.
