Title: Acoustic Barrier with Energy Harvesting
Keywords: acoustic barrier , energy harvesting , micro-fiber composite , piezo materials

Abstract: The present article introduces a new type of piezoelectric barrier with energy harvesting elements. After modelling the noise barriers with COMSOL and conducting experiments, the location of the piezo elements for energy harvesting was determined. The purpose of this article is to test the efficiency optimization of the energy harvesting at noise reduction. The influence of three different typical types of acoustic spectra and different sound pressure levels on the generated electric energy were determined, as well as the efficiency of the acoustic noise power generation system at three different spectra and at different acoustic noise pressure levels on the acoustic barrier
