Abstract
Background: There are few studies reporting on the perceptions of sound quality following cochlear implantation (CI) in everyday listening situations. The current study aimed to determine the subjective perception of sound quality by CI users and identify the relationship between sound quality and health-related quality of life (QoL) following implantation. Method: During this prospective study, 60 postlingual adults (mean age: 53.13±15.19 years; 34 males) who underwent unilateral CI were enrolled. The Hearing Implant Sound Quality Index (HISQUI19) scale was utilized to determine a CI user’s sound quality in everyday listening situations at “one month” and “six months” after implantation. The Nijmegen Cochlear Implant Questionnaire (NCIQ) scale was used to measure the effects of implantation on QoL across pre-CI and “six months” post-CI time intervals. Result: We found a significant improvement in sound quality from pre-CI (mean: 43.56 ± 23.54) to post-CI (mean: 76.86 ± 21.17) phase (p < 0.001). An improvement in sound quality was reported by 89% of CI recipients. A significant improvement in all NCIQ subscales after cochlear implantation was observed (p < 0.001), greatest benefit was in the basic sound perception domain. There was a significant correlation between the total HISQUI19 score and NCIQ subscales. Conclusion: Our results indicated a high-level improvement in sound quality and substantial change in QoL with the CI as a therapeutic option for postlingually deaf adults. A positive correlation between sound quality and QoL parameters suggests that the enhancement of sound quality in these patients can contribute to their improved QoL.
