Study Summary
Satisfaction and benefit from hearing aids fit using two patient self fit methods will be compared against those fit using audiology-based best practices. Individuals between the ages of 50 and 79 years of age will be randomly assigned to one of three fitting methods. Benefit and satisfaction will be evaluated six weeks and six months after the initial fitting.
Primary Outcome
66-item self-assessment, disability-based inventory. Participants answer the questionnaire twice, first prior to use of hearing aids and then after hearing aid use. The questionnaire is scored between 0-99% with higher values representing greater difficulty. Benefit is reported as the difference between the two scores with a higher number signifying greater benefit.
