Fig. 6

Picture of the experiment inside the aeraocoustic wind tunnel (a) and validation-plot for the simulative approach for the two wind velocities considered in this work, 10 km/h and 20 km/h, (b). Plotted are the power spectral densities (PSD) of the sound pressure levels over frequency at KEMAR’s right Eardrum. Plotted in black is the measurement threshold of the artifical head. Depicted in green is the averaged result of the measurements for 15 s measurement time. The grey set of curves represents the measurement results for a measurement time according to the simulation time of 0.5 s. Displayed in orange are the results for the CFD-simulations.
