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 ...

Sounding Mechanism of a Flue Organ Pipe-A Multi-Sensor Measurement Approach. [PDF]

Sensors (Basel)
This 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 chamber using the Cartesian robot equipped with a 3D acoustic vector sensor (AVS) that acquires ...

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.

Nonlinear interactions in organ flue pipes

Journal of the Acoustical Society of America, 1974
The ideas introduced by Coltman and Benade are developed into a quantitative formalism for treating the oscillatory behavior of an air column in nonlinear interaction with an air jet, as in an organ flue pipe or a flute. Explicit solutions are given for the case when the pipe has only two resonances and the nonlinearity is described up to cubic terms ...

Wall losses in straight ducts with non-circular cross sections: a scaling rule of identical losses for wooden flue organ pipes

Acta Acustica
Viscothermal effects at the walls are the dominant sources of loss in the air columns of various types of wind instruments. The classical theory of viscous and thermal boundary layers gives an analytical result that allows for computing the wall losses ...

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.

Resonance phenomena in dielectric media: A review and comparison of acoustic and electromagnetic modes

Journal of Advanced Dielectrics, 2023
The theory and application of resonances and vibrational modes are part of the foundation of science. In this contribution, examples of acoustical resonators are highlighted, and compared to electromagnetic modes.

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.

Transient behavior of flue organ pipes. [PDF]

The Journal of the Acoustical Society of America, 1992
In earlier studies by Fletcher [Acustica 34, 224–233 (1976)], Nolle [J. Acoust. Soc. Am. 66, 1612–1626 (1979)], and Angster and Miklos [Proc. 13th Int. Conf. on Acoust., Vol. 3, 99–101 (1989)] crucial parameters determining the transient behavior of a flue organ pipe have been identified.
