Properties of the Sound of Flue Organ Pipes

Springer Handbooks, 2018
This chapter is an overview of the characteristic sound properties of flue organ pipes. The characteristic properties of the stationary spectrum and attack transient have been surveyed and assigned to properties of the physical systems (air column as acoustic resonator, air jet as hydrodynamic oscillator, and pipe wall as mechanical resonator) involved

Flutes and Flue Organ Pipes

1991
Instruments of the flute type, which are made to sound by blowing a stream of air across a hole in some hollow body, are of extremely ancient origin. Their principal modern descendants are the orchestral transverse flute and the flue organ pipe, but the baroque recorder has been revived during the past 50 years and other instruments, such as the end ...

The Voicing of Organ Flue Pipes

Journal of the Acoustical Society of America, 1951
The art of “voicing” an organ pipe, that is, treating it in order to produce a satisfactory musical tone, is highly developed, but on an entirely empirical foundation. Flue pipes only are dealt with here, chiefly the open diapason, an open metal cylindrical pipe.

Wall Vibrations in Flue Organ Pipes and Their Effect on Tone

Journal of the Acoustical Society of America, 1966
The question of the effect of wall vibrations on the tone of an organ flue pipe is examined theoretically and experimentally. The effect of nonrigid walls is calculated and it is shown that, if they do not affect the pipe frequency, they do not radiate appreciably.

Some voicing adjustments of flue organ pipes

Journal of the Acoustical Society of America, 1979
The investigation uses a flue organ pipe designed so that mouth height Y, position of the upper lip in the air stream X, and width of the air passage are adjustable. Other dimensions can be altered with interchangeable parts. Rectangular and circular resonators of several lengths, open and stopped, are used.

Flue organ pipes: Adjustments affecting steady waveform

Journal of the Acoustical Society of America, 1983
Adjustable flue organ pipes are used in studying the phase and amplitudes of harmonics relative to the fundamental for various horizontal positions of the upper lip, and the behavior of the spectrum as the mean jet velocity is changed in the range 5 to 39 m/s.

A combined LDA and flow-visualization study on flue organ pipes

Experiments in Fluids, 2006
Temporally resolved schlieren flow visualization and Laser-Doppler Anemometry (LDA) measurements have been performed on real flue organ pipes during the stationary state as well as during the attack transient. The techniques prove highly efficient in providing information on the details of the flow.

Tuning and temperament in organ flue pipes

The Journal of the Acoustical Society of America, 1982
The scaling of ranks of organ flue pipes to produce a coherent, characteristic, and tonally balanced ensemble is a problem which has confronted organ builders for many centuries, but the temperament used to tune these pipes has likewise been of concern.

Sound production of flue organ pipes

The Journal of the Acoustical Society of America, 1999
For understanding the sound production of flue organ pipes, the acoustic properties of the two main components, the acoustic resonator and the air jet generator at the labium (flue + upper lip), have been investigated separately. It was found that the formant structure of the stationary sound spectrum is mostly determined by the geometry of the pipe ...

Mode transition of a flue organ pipe

The Journal of the Acoustical Society of America, 2008
A flue organ pipe can be excited in various acoustic modes by changing the air pressure supplied to it. This research aims to reconstruct this behavior from the result of numerical flow simulation of a jet deflected by sound and from physical modeling simulation of the total sound production system.
