Abstract

The high levels of noise pollution can cause physical and mental damage, affecting hearing, being motor vehicles the main source of noise in urban and road environments. One way to mitigate noise dissipation is by installing acoustic barriers that act as obstacles between noise-generating sources and receivers. Acoustic barriers can be made with the addition of minerals, such as concrete, bricks, glass, aluminum panels, wood, acrylic sheets and metal. After the gap is detected in the literature, it is proposed the study of an ideal concrete composition containing rubber and vermiculite residues that meet the required properties for acoustic barriers. At this stage of the project, a dosage study will be carried out to obtain a concrete trace containing rubber and vermiculite residues. Next, we intend to construct two concrete acoustic barrier prototypes, one of them produced with concrete containing rubber and vermiculite residues, and the other produced with traditional concrete. These prototypes will be subjected to tests to determine the level of noise absorption. The set of tests shall provide parameters for the calculation of the total sound intensity level, and the adjustment to the effect of barriers to determine the equivalent level of sound pressure. In this manner, the main technological contributions of this project are the composition of a special concrete for acoustic barriers and the noise tests that are not usually performed in Brazil, presenting a significant advance for this field in a global context.
