Definition:
“Noise Exposure Forecast Contour” (NEF Contour) means a line joining points on the ground in the vicinity or within the boundaries of an airport, which experience equal exposure to noise produced by aircraft using that airport, where each point’s exposure to aircraft noise is calculated for a time in the past or estimated for a time in the future as the combination over all aircraft operations of the integrated time history of each individual aircraft’s noise signature, represented by the unit of Effective Perceived Noise Level (EPNL), scaled and calculated in accordance with section 34.
Period of the Contract:
The period of the contract is for a duration of approximately 15-20 weeks after contract award.
