UHF diaphragm impedance tube

    Acoustic impedance tube is the basic equipment for measuring acoustic material parameters.
Under certain conditions, the sound wave in the pipeline is transmitted in the form of plane wave. In the normal direction of wave transmission, the phase is equal everywhere. Thus, the acoustic signal recorded by the tube wall microphone is the acoustic signal transmitted in the tube.
The incident wave and reflected wave in the pipe can be separated by using the sound pressure transfer function between multi position microphones, and the corresponding material acoustic parameters can be obtained by using appropriate physical relations.
