The article examines time-domain outdoor acoustic simulation of a real-life area using land cover classification identified by airborne hyperspectral imagery. In order to solve the identification problem, the authors presented a classification technique of using airborne hyperspectral imagery for land cover types in a real-life area. The simulation employs a porous-medium model for the solution of acoustic absorption by the surfaces. A validation of the porous-medium model through comparisons with exact solutions is given. The results are compared with those obtained assuming perfectly reflecting surfaces. The source is a coherent linear Gaussian pulse with a full width at half maximum of 1.25m and an amplitude of 1 Pa placed on a road, assuming a road traffic noise source.
