Non-destructive measurement of the pressure waveform and the reflection coefficient in a flue organ pipe
Original language description
A multiple-microphone method employed for in-duct acoustics applications is adapted for a flue organ pipe geometry. In order to make the measurement, non-destructive the microphones are replaced by a pressure probe synchronized with a reference signal. Limits of the method regarding the pipe geometry are verified by the numerical calculations. Acoustic pressure waveforms are reconstructed and a framework for the reflection coefficient calculation is designed and tested.
