Brief Original


This paper is a first study to evaluate the possible use of loose cork granulates as core element in noise barriers. To obtain the acoustical performance of loose cork granulates inside a noise screen, a small prototype of a noise absorbing barrier was designed and compared to commercial rock wool. The results obtained showed that these kinds of porous absorber, specially sorted and prepared, could be good sound absorbers with a certain broadband absorption spectrum.
