Abstract:
Impulsive noise is harmful to human health, and floor impact noise fits into this category. The Brazilian building performance standard sets a minimum requirement of 80 dB for the standardized impact sound pressure level, for floors in the condition of delivery of the work to the user. However in many cases, the apartment is delivered without any flooring. In this manner, even if an apartment delivered to the user meets this criterion with bare slabs, many occupants choose to install ceramic flooring, which can worsen performance by potentially amplifying medium- and high-frequency noise. This study presents statistical results from various field tests comparing bare slabs and slabs covered with ceramic flooring. The findings indicate that floor systems with ceramic coverings and no acoustic treatment tend to perform worse than bare slabs. It supports the inclusion of a criterion requiring rigid surfaces in impact noise testing in Brazil, even in unfinished buildings.
