Abstract

The green materials are products obtained by the transformation of materials of vegetable origin; and they have the advantage that at the end of their useful life, they are scattered in the environment without causing damage. In this work the green material considered and used from acoustic application, is made from giant reeds of sweet water (arundo donax). The giant reeds have been cut, dried and shredded, and a loosened granular material has been obtained, which is very porous, and it presents good characteristics, both in thermal isolation and in acoustic absorption. This paper shows giant reeds application in the room acoustic. Panels with giant reeds shredded were made and they were used in a classroom for the reduction of reverberation time.
