Model for the design of a pressure actuated self-sustained oscillator as an acoustic projector
Stephen C. Thompson · The Journal of the Acoustical Society of America · 2014
Wind musical instruments are examples of a pressure operated self-sustained oscillator that acts as an acoustic projector. Recent studies have shown that this device can also be implemented underwater. However the design parameters for such a device are necessarily different due to the large difference in medium density and acoustic impedance. This paper describes a model that is sufficient to predict the performance of the projector and to understand the effects of design changes on the performance.
