Sounding Mechanism of a Flue Organ Pipe—A Multi-Sensor Measurement Approach [PDF]
SensorsThis work presents an approach that integrates the results of measuring, analyzing, and modeling air flow phenomena driven by pressurized air in a flue organ pipe. The investigation concerns a Bourdon organ pipe. Measurements are performed in an anechoic

The Dependence of Flue Pipe Airflow Parameters on the Proximity of an Obstacle to the Pipe’s Mouth [PDF]
Sensors, 2021 This paper describes the influence of the presence of an obstacle near the flue pipe’s mouth on the air jet, which directly affects the parameters of the sound generated by the flue pipe. Labial pipes of the most common types of mouth were tested.

Pattern Recognition in Music on the Example of Reconstruction of Chest Organ from Kamień Pomorski [PDF]
Sensors, 2021 The chest organ, which gained popularity at the beginning of the 17th century, is a small pipe organ the size of a large box. Several years ago, while compiling an inventory, a previously unidentified chest organ was discovered at St.

On a Robust Descriptor of the Flue Organ Pipe Transient
Archives of Acoustics, 2020 The initial transient of an organ pipe is known to be of great influence to the perceived sound quality. At the same time, the unsteady process of the tone onset is essentially nonlinear and lacks exact repeatability, so the search for a robust ...

Aerodynamics of flue organ pipe voicing [PDF]
International Journal Sustainable Construction & Design, 2010 The objective of this paper is to investigate the possibility of giving useful interpretations of flueorgan pipe voicing practices in terms of the aerodynamical and aeroacoustical behaviour of the pipes. Anoverview is first given of the current state of the knowledge on sound generation in flue instruments.

Attack transient of a flue organ pipe
, 1993 Flow visualizations of the jet formation during the initial phase of the attack transient in a flue organ pipe are presented. These visualizations are related to acoustical pressure measurements inside the pipe. This acoustical response appears to be extremely sensitive to the steepness of the rise of the supply pressure in the foot of the pipe. A fast

Acta AcusticaRecent numerical studies showed that the foot of flue organ pipes closed at one end acts as a Helmholtz resonator and influences the acoustic oscillation in the pipe.

Sound production by organ flue pipes
Journal of the Acoustical Society of America, 1976 A nearly exact, nonparametric treatment is devised to allow calculation of the transient and steady-state acoustic spectra of a flue organ pipe, given the geometry of its construction and the pressure variation in its foot. Explicit formulation is given for the fundamental and the first and second upper partials.

Jet formation and jet velocity fluctuations in a flue organ pipe [PDF]
Journal of the Acoustical Society of America, 1994 Flow visualization of the initial transient in a small recordlike flue organ is presented and the various stages of the jet formation are related to measurements of the acoustic response of the pipe. An initial acoustic signal, due to the unsteady volume flow of the jet, appears before the forming jet reaches the labium.
