ABSTRACT
High noise levels, such as loud, continuous, or frequent sound, can be the cause of frustration and annoyance. Prolonged exposure to certain types of noise can interfere with hearing, sleep, work performance, and general well-being. The regulation of noise and noise control lies primarily with the state and local government. Noise sources in interstate commerce, such as noise from airplanes, are regulated by the federal government. In 1972 the US Environmental Protection Agency announced that a study of airport noise and motor carriers prompted the development of formal noise standards outside of the workplace. Noise and noise abatement laws have emerged throughout the United States to address sounds that are not primarily regulated by the federal government. Some states have passed specific laws that require danger signs warning of amplified sound, that create penalties for excessive horn honking, and that regulate loud car stereo equipment.
