Preventing Noise Exposure in Farmworkers

This study will evaluate a farmworker-level hearing loss prevention training designed to improve hearing protection use among farmworkers exposed to hazardous occupational noise. The intervention consists of a culturally and linguistically adapted, Spanish-language digital training module paired with hands-on earplug fitting and coaching. The primary goals of the study are to (1) assess the feasibility and acceptability of delivering the adapted training in community-based settings, and (2) estimate preliminary effectiveness using an objective measure of hearing protection fit. The study uses a single-arm, pre-post pilot design. A small group of farmworkers will complete pre- and post-training assessments of earplug fit, as well as brief surveys assessing hearing protection knowledge, attitudes, and perceptions. Qualitative feedback will be collected to inform refinement of the training and guide future scale-up. Results will inform the development of a subsequent multilevel intervention that integrates supervisor and organizational components.
