| Research Abstract |
The main objective of this study is to present the essential control of sound and vibration for a strongly-coupled system based on a model consisting of eigenpairs in an explicit form. Firstly, an eigenvalue problem is formulated based on some conditions such as boundary conditions, eigenpairs for the system is then derived. This is followed by validity check of the eigenfunctions using orthotropic condition. Furthermore, a control method of acoustical potential energy based on this model is presented, demonstrating its performance by numerical analyses.
