The purpose of this chapter is to minimize the exposure of citizens to the harmful physiological and psychological effects of excessive noise. The intent of the city council is to control the level of noise pollution in a manner which promotes commerce; the use, value, and enjoyment of property; sleep and repose; and the quality of the environment by establishing maximum environmental noise levels applicable within designated areas or zones of the city; to adopt appropriate exemptions to the provisions of this chapter to allow for the functioning of commercial business and the operation of construction and emergency equipment; and to declare certain noise-producing activities to be noise disturbances.
