Noblesville, IN Noise Ordinances: Aircraft Noise (2026)

Noblesville's general noise ordinance, § 93.25(C), caps sound at levels ranging from 50 dB(A) overnight to 70 dB(A) at any time depending on zoning district, measured from 50 feet away, and makes violation of that cap punishable under § 93.25(G). But § 93.25(F) carves out fourteen categories of sound that never count against those limits, and item (10) reads simply: "Sounds associated with the operation of aircraft or snow removal equipment." Unlike the leaf-blower exemption in item (2) or the construction exemption in item (12), the aircraft carve-out carries no clock restriction and no muffling condition, so it applies at any hour.

This means noise from aircraft using Hamilton County's airspace, including operations tied to nearby general-aviation traffic, cannot be the basis of a Noblesville noise citation regardless of when it occurs or how loud it registers on a sound meter. The city's departments that share enforcement of § 93.25 under § 93.25(H), Code Enforcement and the Noblesville Police Department, have no authority to cite an aircraft operator under this local code; aircraft noise falls instead under federal aviation regulation, not the municipal ordinance. The same subsection groups aircraft with snow removal equipment, another activity the Common Council chose to exempt outright rather than subject to the hourly windows that apply to yard tools and building contractors.
