A Survey Study of Hearing Aid Satisfaction, Quality of Life, and Tinnitus of Elderly Hearing Aid Users

Abstract

Purpose: The purpose of this study is to investigate hearing aid satisfaction, quality of life, and tinnitus of elderly hearing aid users to help hearing aid rehabilitation of the elderly. Methods: A total of 50 elderly hearing aid users (average age 75.7 years) with or without tinnitus participated in this study. We implemented pure tone audiometry and tinnitogram and conducted four questionnaires including Satisfaction with Amplification in Daily Life (SADL), World Health Organization Quality of Life-BREF (WHOQOL-BREF), Visual Analogue Scale (VAS), and Tinnitus Handicap Inventory (THI).Results: Positive correlations were found between SADL and WHOQOL-BREF scores. The average total SADL scores and WHOQOL-BREF scores are 5 points and 3.4 points respectively. There were no significant differences in the average SADL and WHOQOL-BREF scores between the elderly with tinnitus and the elderly without tinnitus. About 90% of the elderly with tinnitus described high frequency tinnitus above 2,000 Hz. Eighty-eight percent of the respondents had an experience of tinnitus therapy and 67% of the elderly with tinnitus therapy experiences reported that tinnitus therapy was not helpful. Ninety-two percent of the respondents stated that wearing hearing aid was helpful to reduce their tinnitus. The emotional and catastrophic subscales of THI were correlated with VAS scores. Conclusion: Positive correlations were found between SADL and WHOQOL-BREF scores regardless of tinnitus presence. Tinnitus of elderly hearing users was not directly related to the quality of life and successful hearing aid intervention could be a key factor in improving the quality of life of the elderly.
