All assembly, educational, institutional, residential, and office buildings located within designated noise impact zones shall be designed and constructed to cause isolation against exterior noise with at least the noise level reduction indicated in the zoning ordinance. For each occupancy, the zoning ordinance specifies the minimum sound level reduction required in each airport noise and accident potential zone (ANAP). An intent of these requirements is to have residential, assembly, educational and institutional, and the like, buildings constructed with sufficient sound isolation so that any habitable room, furnished for normal use and with doors and windows closed, shall be constructed with the noise level reduction as required by the zoning ordinance for each occupancy.
