INTRODUCTION: The main function of hearing is to enable oral communication. Hearing loss impairs communication skills. OBJECTIVE: To evaluate the level of user satisfaction with their hearing aids. METHOD: This is a cross sectionalgroup study comprising of 108 subjects (56% men and 44% women). The average age of the subjects was 77 years. These subjects had been recently fitted with their hearing aids and showed sensorioneural (90%) and mixed (10%) hearing loss as determined via the Questionnaire International Outcome Inventory for Hearing Aids Outcome Inventory - IOI-HA, which determinedthe benefit and satisfaction obtained by sound amplification. RESULTS: The hearing aids improved the quality of life of 52.78% of the patients, which was revealed by their high punctuation (mean=27.3). The relationship of the user with the environment was significantly better (p<0.001) than that of the user with the hearing aid. CONCLUSION: IOI-HA is a simple and easy-to-use tool. Based on the results of this study, we can show ahigh degree of satisfaction with their hearing aids in the majority of the participants, which improved the quality of life. KEYWORDS: Consumer Satisfaction; quality of life; hearing aids.
