Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
Abbreviated Profile of Hearing Aid Benefit (APHAB)
It is a 24-item self-reported measure of hearing disability and hearing aid benefit. It includes four subscales that address different listening challenges: ease of communication, reverberation, background noise, and aversiveness of sounds, with each subscales comprising six items. The ease of communication, reverberation, and background noise primarily measure challenges related to speech communication. The global score on the APHAB is the average of these three subscale scores. The hearing aid benefit is calculated by comparing the difficulty level reported without amplification (unaided) to the difficulty level with amplification (aided). Scores range from 1% to 99%, with higher scores indicating greater perceived hearing difficulty.
T0 = Baseline, T1 = 6 months post intervention, T2 = 12 months post intervention
Secondary Outcomes (5)
Satisfaction with Amplification in Daily Living (SADL)
T0= Baseline, T1= 6 months post intervention, T2= 12 months post intervention
Revised Hearing Handicap Inventory -Screening (RHHI-S)
T0= Baseline, T1= 6 months post intervention, T2= 12 months post intervention
Patient Global Impression of Change (PGI-C)
T1= 6 months post intervention, T2= 12 months post intervention
Connected Speech Test (CST)
T0= Baseline, T1= 6 months post intervention, T2= 12 months post intervention
Quick Speech in Noise (QuickSIN)
