Abstract

Aerodynamic sound from flat plates such as handrail was tested in the low noise wind tunnel. Measurement data was arranged with peak frequency and sound pressure level according to the number of plates, the angle of attack and wind speed. Peak frequency increased step-by-step with the increase of wind speed. Sound pressure level was reduced with attachment on plate edge or blockage of space between plates. The mechanism of aerodynamic sound generation was considered from the change of characteristics.
