How Murfreesboro Handles Noise from Specific Sources: A Practical Guide
Murfreesboro maintains 108 local ordinances across all categories, and 5 of those deal specifically with noise from specific sources. Here is a breakdown of what the city actually requires, what is prohibited, and where Murfreesboro falls on the strict-to-permissive spectrum compared to other cities.
Delivery Truck Noise
Loading, unloading, or handling crates, containers, and garbage cans in a residential or noise-sensitive zone between 10 p.m. and 7 a.m. is banned if it creates a noise disturbance.
Key details: Restricted hours: 10 p.m.–7 a.m.. Zones covered: residential, noise-sensitive. Covers: loading, unloading, crates, cans. Trigger: creates a noise disturbance. Penalty authority: Code § 21-112.
A Noise Control Officer or police officer documents the disturbance and issues a citation under Code § 21-112; each recurring half hour counts as a separate offense.
Bar & Nightclub Noise
Murfreesboro limits sound amplification at bars, cafes, dance clubs and concert venues to 65 dBC by day and 50 dBC at night as measured at the nearest home, plus a 95 dBA in-venue cap unless a hearing-impairment warning sign is posted.
Key details: Daytime limit: 65 dBC, 7 a.m.-10 p.m.. Nighttime limit: 50 dBC, 10 p.m.-7 a.m.. In-venue cap: 95 dBA without warning sign. Measured at: nearest dwelling/noise-sensitive zone.
Enforced by qualified Noise Control Officers; penalties run under Murfreesboro City Code § 1-8, with each half-hour of a continuing violation charged as a separate offense.
HVAC & Mechanical Noise
Murfreesboro doesn't single out air conditioners or heat pumps: continuous HVAC noise is governed by the same 'steady sound' exterior dBA limits in § 21-106(B) that apply to any fixed source, checked at the neighboring property line.
Key details: No HVAC-specific rule: general § 21-106(B) applies. Confirmed by: Code § 21-106(B)(6). Home near commercial HVAC: 53–58 dBA cap. Classified as: steady/quasi-steady sound.
Exceeding the zone's Table 2 limit is enforceable under Code § 21-112 and punished per City Code § 1-8, with each continuing half hour of excess noise charged separately.
Generator Noise
Murfreesboro has no ordinance written specifically for generators: a running generator is a 'sound source' subject to the citywide exterior dBA limits in § 21-106(B), except when it's genuinely being used for emergency work.
Key details: No generator-specific rule: general § 21-106(B) applies. Residential nighttime cap: 43–48 dBA. Emergency-work exemption: Code § 21-109(A)(2). Measured at: neighboring property line.
Exceeding the applicable Table 2 limit is enforceable under Code § 21-112 and punished per City Code § 1-8, with each continuing half hour charged as a separate offense.
Low-Frequency Bass Limits
Murfreesboro's noise code singles out "repetitive bass sounds" as plainly audible noise, and treats bass that's plainly audible in a neighboring unit overnight as automatic proof of a violation.
Key details: Term used: "Repetitive bass sounds," § 21-103(B)(45). Applies: Multi-family units, 8pm-8am. Standard: Plainly audible = presumed violation. Measurement: C-weighting scale for bass.
Bass or music plainly audible in a neighboring apartment or condo between 8 p.m. and 8 a.m. is presumed a violation of Code § 21-106(C)(3), rebuttable only with sound-meter proof of compliance.
The Bottom Line
Murfreesboro'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 Murfreesboro is broadly strict or permissive.
