1 55 dB(A) 7:00 a.m. - 10:00 p.m.
1 45 dB(A) 10:00 p.m. - 7:00 a.m.
In the event the alleged offensive noise consists entirely of impact noise, simple tone noise, speech, music, or any combination thereof, each of the above noise levels shall be reduced by five (5) dB(A).
B. It shall be unlawful for any person at any location within the city to create any noise, or to allow the creation of any noise on property owned, leased, occupied, or otherwise controlled by such person, when the foregoing causes the noise level, when measured on any other residential property, to exceed:
1. The interior noise standard for a cumulative period of more than five (5) minutes in any hour; or
2. The interior noise standard plus five (5) dB(A) for a cumulative period of more than one (1) minute in any hour; or
3. The interior noise standard plus ten (10) dB(A) for any period of time.
C. In the event the ambient noise level exceeds any of the first two (2) noise limit categories above, the cumulative period applicable to said category shall be increased to reflect said ambient noise level. In the event the ambient noise level exceeds the third noise limit category the maximum allowable noise level under said category shall be increased to reflect the maximum ambient noise level.
