Fluctuations in the oscillation of the flue organ pipe—the unsteady steady state [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1979
Although the oscillation frequency of a flue organ pipe can usually be measured within 1% or less, observations of the signal with an oscilloscope may show small, apparently random fluctuations in the waveform. These fluctuations have been investigated with a model pipe having a specially designed flue to discharge turbulence below the jet opening ...

Scanning a flue organ pipe with a p-v probe

open access: yes, 2014
In the course of the last 20 years, a major innovation in the field of acoustic instrumentation regard the development of acoustic velocity sensors based on MEMS technology, now p-v probes are commonly used for sound intensity measurements alongside the p-p ones.

On the intensimetric analysis and monitoring of flue organ pipes

open access: yes, 2005
A short review of intensimetric analysis and monitoring of flue organ pipes based on the new concepts of radiating and oscillating sound intensities will be addressed in this paper. This kind of general analysis dates back to a decade ago when the concept of velocity of acoustic energy transport was rigorously introduced in 1994.
