Killeen, TX Noise Ordinances: Decibel Limits (2026)

Sec. 16-79(a) bans any noise that, on the A-weighted scale with fast response, exceeds 3 decibels over the ambient (background) noise level or a flat 50 decibels, whichever number is higher. On the C-weighted scale, the ceiling is 5 decibels over ambient or 60 decibels, whichever is higher. Measurement is taken at the property line of the noise-producing property or beyond, following the method in Sec. 16-81(e). The decibel ceiling does not replace the general nuisance standard. Sec. 16-79(b) makes clear that even noise under the numeric limit is still unlawful if it annoys, distresses or disturbs a reasonable person of ordinary sensibilities, endangers health or safety, or damages property.

Sec. 16-81(d) sets the measurement protocol: a decibel meter meeting American Standards Association specifications, using the A- or C-weighted scale with fast response, with the microphone held three to five feet above ground and positioned to avoid artificially amplifying or muting the reading. Traffic, aircraft and other transportation noise are excluded from the measurement unless that background noise interferes with the primary sound being measured. Sec. 16-80(a)(5) exempts an activity, such as construction, reconstruction or remodeling done under an applicable permit, if it cannot reasonably be performed in an alternative manner, time or place.

A peace officer who witnesses a violation may arrest on the spot or issue a citation without arrest. Penalties follow Sec. 16-82: $100 to $2,000 for a first conviction, and $250 to $2,000 for a second conviction within twelve months.
