  1. 1. Sound Quality of Flue Organ Pipe. An Interdisciplinary Study on the Art of Voicing

    Författare :Vincent Rioux; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; listening tests; psychoacoustics; verbal descriptors; flue organ pipes; musical acoustics; sound quality; deterministic stochastic separation; timbre; time-frequency analysis;

    Sammanfattning : This thesis presents a research study carried out in collaboration with a department of applied acoustics, a department of musical acoustics and an organ workshop. The description of the sound quality of flue organ pipes has received fairly little attention either in organ-building or scientific literature, despite its importance in the overall quality of the instrument, probably due to the difficulties inherent in doing so.

  3. 2. Sound generation in metal flue organ pipes: On the influence of asymmetric flue exit geometry and vibrations of the upper labium with particular emphasis on the early response

    Författare :Matthias Scholz; Chalmers tekniska högskola; []
    Nyckelord :jet contraction; wall vibrations; CFD; jet velocity profile; tap tone; asymmetry of flue exits; operational deflection shapes; Coanda effect; yielding upper labium; modal analysis; bottom clamped cylinder; vibration measurements; metal flue organ pipes; dipole; initial jet formation;

    Sammanfattning : Sound generation in flue organ pipes is caused by the non-linear interaction between an instable jet and a tube resonator. Our understanding of this very complex physical process is still incomplete, and there is not yet a model that can explain all details of the richness in pipe sound which can be achieved by a trained organ pipe voicer.
