(a) Exemplary scene for the wind noise problem analyzed in this study. A jogger is running at a speed of 10 km/h. Due to the relative speed to the quiescent air (\(u_\infty\)), he is exposed to a flow profile (shown in blue). The region of interest for the simulation (ROI) is shown again in detail. The runner wears either a hearable located in the ear canal (red) or Behind The Ear hearing aids (purple). (b) Sketch of the flow domain in the flow analysis. The head model is positioned at a distance of 0.5 m from the outlet of a wind tunnel nozzle with a cross-section of 0.64 m x 0.48 m. The domain has a total length of 3.0 m, a height of 1.7 m and a width of 2.0 m. The simulation inlet boundary condition is highlighted in green and the outlet boundary condition in orange.
