It can create physical and psychological stress. There is no cure for noise-induced hearing loss, so the prevention of excessive noise exposure is the only way to avoid hearing damage. Specifically designed protection is required, depending on the type of noise encountered and the auditory condition of employee. Earmuffs need to make a perfect seal around the ear to be effective. Glasses, long sideburns, long hair, and facial movements, such as chewing, can reduce protection.
Special equipment is available for use with glasses or beards.
OSHA has promulgated a final rule on requirements for a hearing conservation program. An Industrial Hygienist should conduct sound level monitoring to determine noise exposure levels and the recommended corrective actions. For more specific information on a hearing conservation program see Title 29 CFR 1910.95 - Occupational Noise Exposure. A wide assortment of gloves, hand pads, sleeves and wristlets for protection from these hazards is available. The devices should be selected to fit the specific task.
