"Santa Monica Municipal Code Section 4.12.060 addresses exterior noise standards across different Noise Zones, with adjustments for impulsive or simple tone noise, speech, or music. However, the specific base decibel limits for residential and commercial zones are not explicitly provided in the available snippets. The ordinance often relies on a 'unreasonably disturb the peace' standard, particularly in public spaces due to First Amendment considerations."
