“…Two cylinders were set the distance ratio indicating the characteristic flow (G/D = 0.6, 1.7, 4.9). Previous research showed the characteristic flow [3]. When the distance ratio is large, the vortices generated from the two cylinders are the same as the vortexes generated from independent each single cylinders.…”

“…This matter is also well known phenomenon. There are several flow visualization experiments that when multiple columnar objects are placed in the flow, the flow behind the multiple columnar objects becomes complex [1][2][3][4]. In addition, vortex shedding characteristics which generated from multiple columnar objects are also investigated by measurement experiment using a hot wire anemometer [5][6][7].…”

When a columnar object is put in a flow, Karman vortex is formed, and aerodynamic noise is generated. It is known that when multiple columnar objects are put in a flow, the flow state becomes complex. This can be known by flow visualization experiment. On other hands, there are few researches on flow sound in the case of mutual interference, that it is not as far as the authors know. Measurement of flow sound is performed using a microphone. Therefore, it is necessary to confirm the sound of the interference flow field reaches the microphone outside the flow field without changing. In this research, experiments were measured to confirm flow sound transmits to a microphone placed outside the flow field without changing. Based on the results, the aerodynamic noise measurement from the columnar object was performed using a low noise wind tunnel experimental apparatus. As a result, it was obtained that some findings on the sound of flow in mutual interference flow field
