概要	This paper describes the details of compact wind tunnel with lower noise to investigate the aerodynamic noise generation mechanism. Recent years, high speed running machines, for example bullet train, aircraft, etc., generate the sound which is called wind noise caused by the air flows. This noise makes us uncomfortable and causes a lot of environmental problems. However, few researchers have established a way to reduce the sound. Therefore, the compact wind tunnel would be made. The sound is able to be measured by the wind tunnel. By measuring the sound and the flow velocity around a measuring object, it can find out the correlation between air flows and noise generation, which enables the discussion of noise generation mechanism.
