occupational hearing loss

Loss of hearing for farmers is caused in part by the many potential sources of loud noises on the farm: tractors, combines, grinders, choppers, conveyors, grain dryers, chain saws, shotguns, etc. Prolonged exposure to excessive noise can cause permanent hearing losses, unless noise control measures are taken. The effects of noise can be broken into three areas: 1). Physiological effects: noise induced hearing loss or aural pain, nausea, and reduced muscular control.
