Noise: Controlling Your Exposure at Work - Fact Sheet

There are several ways to protect against exposure to excessive noise levels. Engineering controls involve changes in the work area or equipment; administrative controls involve changes in work procedures. Usually one or the other provides sufficient protection. The law requires that these controls be considered before employees are made to wear hearing protection. If engineering and administrative controls are not feasible or will not provide adequate protection, hearing protection devices, training, and audiometry must be provided to employees.
