(D) When background sound levels exceed those Sound Level Limits identified by the table in 6.18.060(A) due to indistinguishable noise sources (such as but not limited to; freeways, wind, birds, crickets, etc.) a particular sound is not a violation of this Noise Control Ordinance unless it exceeds a Leq of 5 dB(A) above the background sound level. Appropriate noise level measurements will be taken on the receiving property to determine the background noise level and the level of the suspect sound. If the suspect sound is determined to exceed a Leq of 5 dB(A) above the background sound level, the creation of this sound is a violation of the ordinance.
