Abstract
Wind tunnel testing on aerodynamic sound from perforated metal was conducted. Sound pressure level and peak frequency were analyzed. Firstly, experimental setup was customized for targeted aerodynamic sound. The sound was measured at angle of 80 degree, with wind speed of  less than 12.5 m/s. Peak frequency around 1 kHz is proportional to wind speed, which depends on hole diameter.
