Paper Abstract

Passive tuned vibration absorbers (TVA) are widely used in reducing vibrations in machinery, buildings and many other vibrating structures. Recently, TVAs have been installed on structures for the purpose of reducing the sound radiation from the structure. As in the case of vibration control, the tuning and placement of TVAs for noise control is often based on the forced response of the structure, as opposed to the behavior of structural-acoustic interaction. This conventional approach for TVA placement on structures is not always effective for controlling sound radiation from the structure. This task requires proper control of the structural waves that couple well with the acoustic environment. This paper presents a preliminary study of acoustic radiation and radiation efficiency of panels instrumented with passive TVAs.
