Organ and its Sound

The project focuses on the physical principles of organ pipe sound and the influence of the labia settings (labia intonation adjustments) on the perceived sonic properties. The project was intended to obtain new insights into organ acoustics for artists, organ specialists and listeners and to process them into a monograph titled Organ Pipe Tone. The knowledge obtained was also published in impacted periodicals and the transparent model of an organ pipe developed as part of the project is also used in the NAKI II follow-up project (for all results, see MARC Publication Results).
