How Knoxville Handles Noise from Specific Sources: A Practical Guide
Knoxville maintains 133 local ordinances across all categories, and 2 of those deal specifically with noise from specific sources. Here is a breakdown of what the city actually requires, what is prohibited, and where Knoxville falls on the strict-to-permissive spectrum compared to other cities.
Generator Noise
Knoxville bans unmuffled generator and stationary-engine exhaust noise citywide, requiring a muffler or equivalent device that prevents loud or explosive sound, whether or not the decibel standard in Section 18-3 is exceeded.
Key details: Governing section: § 18-4(c)(3), Exhausts. Requirement: Effective muffler on stationary engines. Covers: Generators, motorboats, motor vehicles. Max fine: $50 plus up to $500 costs.
Violating Chapter 18 carries the Code's general penalty: a fine up to $50, up to $500 in administrative costs, and/or up to 30 days in jail, each day is a separate offense (§ 1-9).
Low-Frequency Bass Limits
Knoxville limits car stereo and bass noise to what's audible 50 feet away, whether on public streets or from private property, and it explicitly counts bass reverberation as regulated sound even when lyrics aren't understandable.
Key details: Governing section: § 18-5, vehicle audio equipment. Audibility limit: 50 feet from the vehicle. Bass explicitly covered: Includes bass reverberation. Applies to: Public streets, parks, private property.
Same general penalty as all Chapter 18 violations: fine up to $50, up to $500 in administrative costs, and/or up to 30 days jail; each occurrence is a separate offense (§ 1-9).
The Bottom Line
Knoxville's noise from specific sources rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Knoxville is broadly strict or permissive.
This guide is based on Knoxville's current municipal code. Local rules can and do change, so check the individual ordinance pages for the latest details, penalties, and FAQs.
