Resumen
This study aims to evaluate the acoustic performance of precast slabs, made with different filling materials when subjected to impact. Filling materials used in this research are: EPS (Expanded Polystyrene), Ceramic tile and Cellular Concrete. For the analysis, three slabs of reduced dimensions were assembled, and then subjected to impacts that generated noise, enabling the analysis of data collected through the noise meter. It was found that despite the differences of the materials tested, the variation of the decibel levels is not as significant, and that the materials have a similar and performance.
