Purpose: The aim of this study was to survey the satisfaction of hearing aid users in Korea. The questionnaire was designed to find out not only the satisfaction of wearing hearing aid but also the various viewpoints about the hearing aid itself of its wearers. Methods: A total of 118 subjects including 72 males and 46 females completed the survey from 28 hearing aids centers. The questionnaire was divided into two parts. The first part contained the audiological information reported by the experts and the other part included about the information of hearing aid performance, listening environments and related services reported by the hearing aid users. Results: Overall satisfaction rate of hearing aid was 64.4%. About 84% of the subjects answered that the hearing aid made their quality of life improved. The most satisfied function of the hearing aid was ‘overall comfort,’ the most satisfied sound quality was ‘improved hearing ability,’ the most satisfied listening environments was ‘one-to-one conversation,’ and the most satisfied service quality was ‘kindness of the staffs.’ The most important listening situation they thought was ‘communication with cell phone.’ The proportion of using customized hearing aid was 77.9%, bilateral fitting rate was 62.4% and average purchasing price was 1,820,000 won per a unit. Conclusion: The overall hearing aid satisfaction rate (64.4%) was lower than USA (81%) and Germany (76%) but higher than Japan (38%). In Korea, the comprehensive study for the hearing aid market, specific satisfaction viewpoints of the hearing aid wearers and the status of non-wearers who have hearing loss should be needed for improving the user’s hearing aid satisfaction rate in the future.
