Official Decibel Limits
volume_up"Chapter 8.19.110 refers to sound level limits in tables, but distinct day/night numerical limits for receiving residential and commercial properties are not explicitly delineated in the provided text of "Table 1 Sound Levels by Receiving Land Use." However, "Day-Night Average Sound Level (Ldn)" is defined, where levels between 10:00 p.m. and 7:00 a.m. are increased by 10 dBA for averaging purposes, indicating stricter enforcement during nighttime. Table 1, though ambiguously formatted in the search results, generally indicates limits such as 55 dBA for residential receiving from residential emitting, and 45 dBA for residential receiving from business/commercial emitting. Motor vehicle and motorcycle sound limits measured at 15 meters (50 feet) are 86 dBA for vehicles 10,000 lbs or more, 82 dBA for motorcycles, and 76 dBA for other motor vehicles. Recreational motorized vehicles have a limit of 86 dBA."

Specific Noise Restrictions
Construction
Specific hours for construction and demolition are not explicitly stated as restricted, but these activities would be subject to the general noise disturbance prohibitions, especially during quiet hours (10:00 p.m. to 7:00 a.m.).
Amplified Sound
It is unlawful to operate amplified sound devices during nighttime hours in a manner that creates a noise disturbance across a real property boundary or within a noise-sensitive area, or during daytime hours in violation of decibel limits. Additionally, any amplified sound from a residence, business, or fixed location that is audible 150 feet or more from its origin, or causes a vibration 300 feet or more, constitutes a simple misdemeanor.
Animals
Excessive, unnecessary, or unusually loud noise that disturbs the peace, health, quiet enjoyment, or safety of a reasonable person, including animal noise, is prohibited, especially between 10:00 p.m. and 7:00 a.m. Animal control handles reports of animals running at large, abuse, and neglect.
Vehicles
Operating a motor vehicle or motorcycle with a sound level exceeding the limits specified in Table 2 (e.g., 86 dBA for heavy vehicles, 82 dBA for motorcycles, 76 dBA for other vehicles at 15 meters) or otherwise creating a noise disturbance is unlawful. Recreational motorized vehicle sound limits are 86 dBA.
