Summary
New single-family homes built after November 25, 2010 inside Tinker AFB's DNL noise contours must meet strict sound insulation standards, capping average interior aircraft noise at 45 decibels under the city's Airport Zoning Ordinance.
All new single-family detached residential uses permitted after November 25, 2010 shall achieve an average interior sound level of not more than 45 decibels (dB).
In order to achieve an average interior sound level of not more than 45 dB within APZ, sound level reduction (SLR) standards shall be used in new construction.
The U.S. Air Force has established sound reduction standards designed to provide outdoor-to-indoor SLR of 25 dB, 30 dB and 35 dB. The requirements within this subsection are in agreement with the 2008 JLUS.
The overall SLR required within a given noise zone can be determined by subtracting the required level (45 dB) from the highest noise level within that contour. For example, at the 70 dB DNL, the required reduction to obtain an internal 45 dB for residential structures is calculated as 70 dB minus 45 dB equals 25 dB.

Full Breakdown
Midwest City's Airport Zoning Ordinance (Appendix B, adopted by Ord. No. 3132 in 2010) sets mandatory sound attenuation construction standards for new single-family homes inside Tinker Air Force Base's DNL noise contours, shown on the city's Airport Zoning Map. Depending on the zone, 65-70, 70-75, or 75-80+ dB DNL, builders must hit sound level reductions of 25, 30, or 35 decibels using specified wall, window, door, roof, and ventilation assemblies, so interior noise never tops 45 dB. A building permit is required, and the Board of Adjustment can grant variances for practical difficulty or hardship.
Violations & Fines
Violating the Airport Zoning Ordinance is a misdemeanor punishable by up to a $500 fine, up to one year in the county jail, or both, under Midwest City Code § 6.5.1.
