If, at any time, the police department determines that the sound produced by an amplified sound system in a park is unreasonably interfering with other persons using the park or with nearby residents in the comfortable and reasonable enjoyment of their premises, an officer shall request the person in charge of the assembly, or any other person appearing to be involved in the production of sound, to immediately reduce the level thereof. If the sound is not reduced within five minutes to a reasonable level, the officer shall immediately contact the parks maintenance division personnel to curtail the power source. (Ord. 127 § 3.10, 1994)
