The purpose of this study is to identify and describe noise exposures and hearing loss among farmers, to explore factors that influence farmers‚ a high-frequency pure tone average hearing thresholds, and to evaluate changes in hearing over time due to a point-source intervention. The intervention consisted of a box containing hearing protection devices placed near loud noise sources on the farm. Maximum noise exposures were at 102 dB. Farmers have high-frequency hearing loss. Standard threshold shifts and high-frequency notches were identified, many affecting left ears. Farmers in the control group had poorer low-frequency hearing than farmers in the intervention group (p=0.01). Farmers experience high-frequency hearing loss. Left ears were less sensitive than right ears. Presbycusis is evident in the study population. However, sensorineural hearing loss appears to be common among this group of farmers especially in the left ear. Long-term follow-up is warranted.
