COMPARATIVE ANALYSIS OF MATS’ PERFORMANCE IN IMPACT NOISE BETWEEN FLOORS

Abstract

This study evaluates the effectiveness of PET wool and recycled tire rubber mats in reducing impact noise between floors, according to ABNT NBR 15575 (2021). Three reduced-scale prototypes, with and without mats, were built and tested in laboratory following ISO 10140-3 (2021). The rubber mat showed better performance, reaching the intermediate level of the standard and approaching the superior level. Results indicate that recycled materials are a sustainable and efficient alternative for acoustic comfort in residential buildings
