Induced noise control

A technique by which to achieve noise control in a dynamic system, referred to herein as a master dynamic system, is to couple it to another, an adjunct dynamic system. The resulting induced noise control is defined in terms of the ratio of the energy stored in the master dynamic system when coupled to the adjunct dynamic system to the stored energy in the master dynamic system in the absence of this coupling. An analytical description for the induced noise control is developed. The analysis is then used to define the dependence of the induced noise control on the parameters that define the two dynamic systems and the coupling between them. An appropriate induced noise control may then be designed and implemented. Also, the relationship of this energy analysis to the statistical energy analysis is briefly discussed.
