The aim of this paper is to investigate the noticeable flutter or amplitude modulation that may accompany the sound of an organ pipe. For pureness of tone it is important that the wind supply is perfectly steady and without any imperfections that may influence the pipe tone and cause pipe flutter. For many years Pipe Organ Builders have been aware of flutter that is present when voicing and tuning organ pipes and some have tried to address this problem with little success. This is investigated in the frequency domain using noise and vibration measurements for different combinations of fan and reservoir types operating at various wind pressures. Preliminary measurements indicate that under certain conditions, the fan excites the reservoir at its resonant frequency with sufficient amplitude to cause unwanted modulation.
