In order to predict aerodynamic sound, it is necessary to measure surface pressure fluctuations or distribution of a vorticity fields. The space measurements of these values are quite difficult. Then the predictions of aerodynamic sound are hard by using the conventional fluid dynamics measurement tools. Recently, PIV and PSP are candidates of breakthrough technique for aeroacoustics measurements. In this paper, I introduce some examples applied to aeroacoustics investigation to PIV and PSP.
