Resumo

Since the 2013 has been approved the new rule performance in buildings, NBR 157575, the standard have one item for acoustic evaluation, and for evaluate the capacity of acoustic isolation of a commercial and regional materials for the impact noise isolation. The present study has been realized using an industrial and regional acoustic insulation, and waterproof rubber. The tests have done with reverberant chamber in scale and the samples of concrete slab for simulate the real building. The results, when compared with the NBR 15575 standard show that the levels of impact noise are in an allowed level for the commercials materials and the regionals materials.
