This proposal presents the phased development of a Decision Support System for Aircraft Environmental Noise Impact Prediction. The Decision System has several components including an acoustic source modeling component, an acoustic propagation component, a visualization/audio component, and an applications module. The technical basis for the system is the adaption and refinement of source and propagation noise models successfully employed in undersea acoustic simulation and modeling to the modeling of aircraft noise and atmospheric propagation. Phase I will define modeling and simulation approaches and components necessary to the development of a digital model database for noise emitted by fixed and rotary wing aircraft, the propagation of this noise through the atmosphere, and the sound pressure levels experienced by human and animal populations in the resulting acoustic fields.
