- Proposal
This ordinance establishes noise regulations for Oklahoma City by declaring excessive noise a public nuisance and detriment to public health and safety. The document defines key terms used in noise enforcement, including ambient sound pressure level (measured as L90, the noise level exceeded 90 percent of the time over a 10–30 minute period), A-weighted sound level (measured in dB(A)), continuous sound (any sound lasting six minutes or more), and decibel as the unit of measurement. The ordinance specifies that construction excludes demolition activities and establishes definitions for mechanical devices used in noise assessment, though the full text is incomplete. The findings declare that noise levels in the City have increased over time and that scientific methods exist to measure and abate excessive noise as a matter of public policy and legislative determination.
