Method of Analyzing the Wind Tunnel Test Data Measured with Directional Microphone Systems

In order to clarify the characteristics of aerodynamic noise generated by high speed trains, wind tunnel tests are repeated and directional microphone systems, such as an acoustic mirror system, are generally used to localize the sources of aerodynamic noise. This paper explains the theoretical back...
