In this note, the results are presented of some analytical and numerical studies on the active control of non-linear panel vibrations and sound radiation due to wall pressure fluctuation. In our previous work [1], we treated the problem of passive control of non-linear panel vibration by boundary da

An important cause of sound radiation from a submarine in the low frequency range is fluctuating forces at the propeller. The forces are transmitted to the hull via the shaft and the fluid. Sound radiation occurs due to hull and propeller vibrations as well as dipole sound radiation caused by the op

The idea of active control of sound dates back to Paul Lueg in 1934 but it was not until the 1980s that a device, based on analogue componentry, came close to any practical application. Since then the advent of modern digital computing and digital signal processing has vastly advanced the possibilit

This paper reports an investigation of the active control of sound radiation from vibrating surfaces by using arrays of discrete actuators, or tiles, which cancel local volume velocity. The radiation of sound can be controlled by reducing the vibration levels on the structure and by changing its rad
