Abstract
The present study has the goal of showing the acoustic performance of materials routinely used in Brazilian building construction. In situ measurement procedures are presented for the determination of acoustic performance of the materials. Measurements were performed according to the standards ISO 140-4, ISO 140-5, and ISO 717-1. The results were compared with values for sound insulation prescribed by the German Standard DIN 4109. The performance of Brazilian building materials were shown to be below international standards of acoustical quality.
