ANALYSIS OF ACOUSTIC FIELD EMITTED BY ORGANS: A CONTRIBUTION FOR THE TUNING OF ANCIENT INSTRUMENTS

摘要

This work is devoted to the study of the acoustic field produced by flue organ pipes. Several experiments have been performed in order to investigate the characteristics of the acoustic wavefield with the aim to provide an objective method for the restoration and tuning of organs. We study the behaviour of the pipes when they are excited by different levels of blowing pressure and when a single pipe is played in presence of another even silent. Synchronization and shifts in frequency occur.
