Evaluating the Clinical Effectiveness of a Community-based Hearing Aid Fitting Service Delivery Model Facilitated by Community Healthcare Workers (CHWs) Providing Smartphone-based In-situ and Pre-set Hearing Aid Fittings in Low- and Middle-income Communities (LMICs)

The purpose of this study is to advance hearing care in low- and middle-income countries (LMICs) through the rigorous evaluation and optimization of innovative interventions and technologies. This study encompasses the following key aim: This study aims to establish the effectiveness of community-based hearing aid fittings facilitated by community healthcare workers (CHWs) using mobile health (mHealth) technologies in low- and middle-income communities (LMICs). The primary goal is to determine the efficacy of CHW-facilitated smartphone-based in-situ hearing aid (HA) fittings (a proprietary fitting based on the NAL-NL2 algorithm) and pre-set HAs fittings compared to minimal amplification through a single-blind randomized controlled trial (RCT). By comparing self-reported benefits between the experimental and control groups, this aim seeks to demonstrate the superiority of the CHW-facilitated smartphone-based and pre-set hearing aid fittings compared to minimal amplification.
