Imaging standing waves in the resonator of a flue organ pipe
The Journal of the Acoustical Society of America, 2022The acoustic standing wave inside a transparent flue organ pipe has been imaged using transmission electronic speckle pattern interferometry (TESPI). Optically imaging acoustic standing waves in a pipe requires sensing the pressure-induced change in index of refraction of the air, and imaging this change in index has been accomplished in the past using

The influence of pipe scaling parameters on the sound of flue organ pipes
The Journal of the Acoustical Society of America, 2004When basic phenomena of the physics of flue organ pipes is studied, experiments on models are acceptable. But these models often differ considerably from real organ pipes. For this reason the fine details of pipe sounds should be investigated on real pipes. The sound quality of an organ pipe is mainly influenced by the attack transients.

The Physics of the Organ Flue Pipe
American Journal of Physics, 1953This is a review article in which the physical principles underlying the function of the organ flue pipe are considered. Many of the points are not understood, and attention is called to them as possible lines of investigation. A survey is made of the various theories of the action of the airstream at the mouth of the pipe; details are given of the ...

On the acoustical design of the ears of flue organ pipes
The Journal of the Acoustical Society of America, 2004Application of the ears to the flue organ pipe is one of the important voicing techniques. Ears are the projections on both sides of the pipe mouth. Organ builders say the ears make not only the sound lower and darker, but also the buildup of tone smoother and quicker. The aim of this research is to confirm their recognitions and make the causes clear.

The effect of resonator shape on air flow in flue organ pipes
The Journal of the Acoustical Society of America, 2021The effect of changing the shape of the resonator of a flue organ pipe was studied in a replica of an organ pipe that was printed using transparent media. The pipe was designed so that the rectangular resonator could be replaced by a cylindrical one of the same cross sectional area, and the airflow in the pipe was imaged using high-speed transmission ...

The physics and sound design of flue organ pipes
The Journal of the Acoustical Society of America, 2012Sound design methods for flue organ pipes can be developed for the practical application in organ building due to the high performance of modern computers and the advanced level of the scientific research on flue organ pipe acoustics. The research of Neville Fletcher and the team around him has contributed in a high extent to the scientific ...

Analyses of Verbal Descriptions of the Sound Quality of a Flue Organ Pipe
Musicae Scientiae, 2001This paper presents two exploratory experiments aimed at establishing a lexicon suitable for the description of the sound quality of flue organ pipes. A lexicon of reference was established by an expert organ-builder commenting several voicing steps performed on a flue pipe.

Simulation and measurement of wall vibrations of a flue organ pipe
The Journal of the Acoustical Society of America, 1999The question of whether the vibrations of a metal flue organ pipe contribute to the perceived sound or not is still not completely answered. One result of the research done within the GOArt (Göteborg Organ Art Center) project is that, due to the casting process and the need to save material, the baroque flue organ pipe has considerably thinner walls ...

End behavior of the acoustic standing wave in a flue organ pipe
The Journal of the Acoustical Society of America, 2023The acoustic standing wave in a transparent flue organ pipe has been imaged using high-speed transmission electronic speckle pattern interferometry. Spectral filtering of the interferograms at the acoustic resonance frequency of the gas inside the pipe results in an image showing the sinusoidal pressure dependence inside the pipe as well as the ...
