Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this project is to compare the effectiveness of several approaches to influencing hearing protector use. The goals of this study are to further develop an intervention to promote farmers' use of hearing protectors, and compare the effectiveness of the developed intervention with two alternative approaches to influencing hearing protector use behavior, delivered in various combinations. This study will determine if significant change in hearing protection use can be achieved in a one-shot web-based or protector-supply intervention. Results will determine the need for future program modifications, e.g., inclusion of booster(s).
