It is the intent of the city to incorporate into this chapter those standards of measurement hereinafter set forth, which will take into account the latest scientific advances in noise measurement and control while at the same time preserving the common sense and common law determination of what constitutes a disturbance or public nuisance. Therefore, sound level measurements, while universally desirable, shall not be required to demonstrate violation of this chapter if other evidence or testimony establishes the creation of a disturbance or public nuisance. (1984 Code § 8.28.020)
