Intelligent Control of Noise and Vibrations in Building
Building acoustics is an important issue because it is related to human comfort and the quality of the indoor environment. The plate-like structure, such as a door, window, floor and wall, is one of the most common types of construction and building. In this work, the experimental and numerical characterization of the acoustic performances of walls and double walls found in building is investigated. First, the acoustic performances of windows in the exterior building façade are evaluated experimentally according to the standard norm ISO 10140. In the second part of this work, a finite element formulation for sound transmission through double wall panels is presented. The third part of this paper concerns the control of sound transmission through double panels using semi-passive piezoelectric shunt technique. More specifically, the system consists of two walls with an air cavity in between. The external panel has surface-mounted piezoelectric patches. The piezoelectric elements, connected with resonant shunt circuits, are used for the vibration damping of some specific resonance frequencies of the coupled system in the low-frequency range.
