Abstract:
A noise structure having a barrier made of a generally sound redirecting material defining a surface of the barrier, and a plurality of sound absorbing boxes connected to this surface, each box comprising a rear wall and an extensively perforated front wall, the walls defining a longitudinal channel at least partially occupied by a filling made of a sound absorbing material, in which the rear wall is a substantially flat plane wall assembled parallel to and spaced apart from the surface of the barrier and is in its turn extensively perforated.
