Full Breakdown
Section 9.08.050 lists two overlapping nighttime-quiet provisions. Subsection B, Radios, Stereos, Etc., bars playing or operating a radio, stereo or sound amplifying equipment in a manner that disturbs the peace, quiet and comfort of neighboring inhabitants, and it goes further for the night window: operating any such equipment between 8:00 p.m. and 7:00 a.m. in a manner audible to a property or structure adjacent to the building, structure or vehicle from which the sound comes shall be prima facie evidence of a violation of the section, meaning the city need not separately prove the sound was unreasonable once it clears that audibility and time threshold.
Subsection D, Yelling, Shouting, Etc., applies the identical prima facie structure to yelling, shouting, hooting, whistling or singing in a residential or commercial area between the same 8:00 p.m. and 7:00 a.m. hours. Both clauses sit inside the non-exclusive list of loud-or-raucous-noise acts declared unlawful by Section 9.08.020 and the policy statement in Section 9.08.010, which finds that loud or raucous noise is detrimental to public health, welfare and safety and constitutes a public nuisance that may be abated as such. Section 9.08.060 supplies the penalty: a misdemeanor or infraction at the prosecuting authority's discretion, each violation a separate offense, a service fee for repeated calls to the same address within 24 hours, and nuisance abatement under Chapter 8.16 for chronic offenders.
