A hard screen on an absorbing ground is investigated experimentally under the influence of wind. The experimental data are the result of model experiments in a 1:25 scale model within a wind tunnel. The sound propagation is measured using a triggered spark source and averaging on a power basis in the frequency domain. The meteorological data representing the wind conditions have been determined by means of hot-wire anemometry in positions on both sides of the screen as well as directly over the screen. The measured data are compared with calculated results from PE calculations and from an alternative ray oriented approach based upon the use of diffraction theory for the screen.
