Visualization of flow features in the transversal plane of a human head which are masking sound waves noticed by the human ear. At the head exposed to frontal flow (blue), detachment occurs at the temple and in the area of the pinna. This results in a sound pressure signal (wind noise), which is particularly strong in the low-frequency range and decreases towards higher frequencies. The superimposition of the sound signal and the flow results in a masking of the useful sound signal by wind noise. Especially in the low-frequency region, the wind noise is masking the sound signal.
