Active control applied to simplified wind musical instrument

Meurisse, Thibaut; Mamou-Mani, Adrien; Caussé, René and Sharp, David (2013). Active control applied to simplified wind musical instrument. In: 21st International Congress on Acoustics, 2-7 Jun 2013, Montreal, Canada.




Active control is widely used in industry. However, there have been relatively few applications to musical instruments, particularly wind instruments. The aim of this study is to attempt to control the sound quality and playability of wind instruments, using active control. Active control makes it possible to modify the input impedance (amplitude and frequency) of an instrument and to modify the instrument's quality. Simulations and first experiments on a cylindrical tube, which is considered to be a simple wind instrument, with embedded microphone and speaker are presented. Finally, the effects on the sound and the input impedance of the instrument are studied.
