Abstract
Content

The Rotorcraft Noise Model (RNM) is a suite of computer models that predicts far-field noise for single or multiple flight vehicle operations. RNM calculates the effects of sound propagation over varying ground terrain for acoustic sources using geometrical theory of diffraction algorithms, and through a horizontally stratified atmosphere over uniform terrain with winds. RNM calculates the noise levels in the time domain and with a variety of integrated metrics at receiver positions on or above the ground at specific points of interest and over a uniform grid.
