§ 150-121  Purpose.
   The purpose of this building code amendment is to establish standards of isolation against exterior aircraft noise for areas in the vicinity of the MCAS and Yuma International Airport where the exterior day-night sound level (Ldn) exceeds 65 dB.  The amendment requires buildings in such noise zones to be so designed and constructed as to isolate them appropriately from the exterior noise exposures.
