About the study
The research will explore outcomes of different service delivery models of over-the-counter (OTC) hearing aids by comparing them to prescription hearing aids fitted by specialists in individuals with mild to moderate hearing loss. The investigators will examine how each type affects users' experiences, behavior, thinking skills, and brain activity related to hearing. Additionally, the study will focus on what types of people prefer each hearing aid option, what helps or hinders these choices, and compare the costs of four different service options. This approach will help transition from research findings into real-world practice, providing useful information for healthcare providers and policymakers about OTC hearing aid options.
