The amount of continuous exposure to high noise levels must be limited. For hearing protection, scheduling noisy operation for short intervals of time each day over several days is preferable to a continuous eight-hour run for a day or two.
In industrial or construction operations, an intermittent work schedule benefits not only the operator of the noisy equipment but also other workers in the vicinity. If an intermittent schedule is not possible, workers should have relief time during the day. They should take their relief time at a low-noise-level location and should not trade this time for more pay, paid vacation, or an early out at the end of the day!
Inherently noisy operations, such as street repair, municipal trash collection, factory operation, and aircraft traffic, should be curtailed at night and early morning to avoid disturbing the sleep of the community.
