Use of Radiation Efficiency in Noise Control Engineering
Abstract
The radiation efficiency is defined in terms of the power that is radiated by a structure, the absolute square of the normal velocity on the surface integrated over that surface, and the characteristic impedance of the fluid facing the surface. The utilization of the radiation efficiency as a useful engineering quantity for describing the radiation from panel-like structures and for the estimation of the effectiveness of measures that may be used to control the radiated power from such structures is questioned. Caution needs to be exercised in the use of the radiation efficiency for these purposes.
