Supervisors will also receive brief training on how to support hearing protection use in the workplace.\n\nParticipants will wear a small device (dosimeter) during a work shift to measure noise exposure before the program and again about one month later. Participants will also complete surveys about their knowledge, attitudes, and behaviors related to hearing protection.\n\nA subset of participants will be invited to take part in interviews to understand barriers and facilitators to using hearing protection and implementing the program.\n\nThe results of this study will help inform future efforts to improve hearing health and reduce noise exposure in agricultural settings.",[73,74,75],"Noise Exposure","Hearing Loss, Noise-Induced","Occupational Exposure",[77,78,79,80,81,82,83,84,85,86],"farmworkers","agriculture","hearing protection","earplugs","occupational noise","hearing conservation","implementation science","Community Health Workers","Workplace intervention","Cluster randomized trial","NOT_YET_RECRUITING","2026-04-21",{"date":90,"type":91},"2026-04-28","ACTUAL",{"date":93,"type":67},"2026-10",{"date":95,"type":67},"2032-07",{"name":5,"class":6},1]
