Abstract
Different techniques, both active and passive, are available to reduce the noise. Usually the energy associated to the noise is dissipated; anyway it may be recovered and stored, or used to drive other devices to counteract noise, without additional active electrical components. The energy can be directly converted from mechanical into electrical form using thin piezoelectric patches making a complete self-supplied system for noise control. The basics of this principle are here reported. In order to prove the goodness of the principle, a deep investigation using FEM tools has been performed. Some FE commercial software allow to take into account the interaction between fluid and piezoelectric structure and make possible to introduce in the model an electrical network. An original complete fully coupled (Fluid-Piezo Structure-Electrical Network) FE model is presented and different layouts for piezo panel absorbers are investigated. Together with the simulations, experimental trials have also been made. The experiments validate the model and the results are reported. Both the simulations and the experiments show clearly that the proposed solution can be a smart and inexpensive alternative to the classical systems. Moreover many interesting applications can be based on this system.
