Noise is usually considered one of the main sources of "outdoor pollution". It may be produced by different sources due to human activities: transport systems, industrial and trading plants, yards and recreative activities. Noise barriers are one of the most commonly employed systems to reduce noise by transport infrastructures. An original noise barrier is here proposed. The barrier is constituted by a concrete base, porous materials and a multi-holed resonant panel (MHRP). Experimental tests were carried out in order to evaluate MHRP performances and the optimum configurations for maximum acoustic absorption.

Abstract
Noise is usually considered one of the main sources of "outdoor pollution". It may be produced by different sources due to human activities: transport systems, industrial and trading plants, yards and recreative activities. Noise barriers are one of the most commonly employed systems to reduce noise by transport infrastructures. An original noise barrier is here proposed. The barrier is constituted by a concrete base, porous materials and a multi-holed resonant panel (MHRP). Experimental tests were carried out in order to evaluate MHRP performances and the optimum configurations for maximum acoustic absorption.File in questo prodotto:
