摘要
SI (Sound Intensity) measurement using the two-microphone method is still a young technology but it offers great possibilities in the area of sound-intensity analysis, particularly for sound sources with complex shapes. This report describes the characteristics, performance and technological problems of sound-intensity analyzing equipment by using Ono Sokki's dual-channel FFT analyzer CF-900 as an example.
