Determination of the Sound Absorption Capacity of Hydraulic Concrete Mixtures Added with Waste Tire Rubber

There are different types of pollutants that harmful to the environment, including smog, chemicals dumped into rivers, scrap tires, etc. The latter have particularity it is not possible recycle them manufacture new tires. In present work, hydraulic concrete plates added with waste tire rubber were manufactured modify their sound absorption capacity. It was found additions produce changes in density material and When exposed high-frequency sounds correspond high-pitched sounds, its capacity increases. On contrary, when test frequency low, is, bass decreases. results obtained this work suggest proposed mixtures suitable for acoustic insulating shields.
