Low frequency vibration approach for assessing performance of wood floor systems

TL;DR: In this article, a low frequency vibration method was used to assess the structural performance of wood floors as component systems, and the results indicated that the forced vibration method is capable of measuring the fundamental natural frequency (bending mode) of the wood floors investigated.

Optimal vibration control for structural-acoustic coupling system:

TL;DR: In this article, a static output feedback controller for a structural-acoustics coupling system using piezoelectric actuators is proposed, and the response of the coupled system is obtained using Galarkin's method.
