About article:
This paper aims at an experimental evaluation of the quality of the wood used in the
manufacture of wooden organ pipes. For this purpose we created a stock of pipes, using
various types of wood for the walls of the pipes and for the front board. Using this trial stock
of pipes, we conducted a series of experimental measurements, proceeding from an analysis
of the sound spectrum. It was shown that what exerts the most fundamental influence on
the quality of the sound spectrum is the measure of the pipe and its intonation. This reality
is confirmed by the fact that despite the use of varying materials and varied thickness of
walls, under constant conditions (pressure, temperature) the resonance mode of all the pipes
examined is at the same frequency. A further finding is that the material of the front board
and walls may under certain conditions and circumstances have an influence on the creation
of a disturbing (humming) component of the tone of the pipe, and indeed on the creation
of harmonic tones. Even a small change in the original tuning of a historical pipe causes
a relatively marked changes in the actual sound system of the pipe. This fact has significant
consequeces in the field of restoring historical organs and on changes to the tuning of those
instruments.
