Sound absorption panel
A sound absorption panel system and method of manufacture for absorbing railway or vehicular noise, the system comprising a plurality of sound absorbing panels 10 disposed adjacent to each other in an end to end configuration, wherein each sound absorbing panel comprises: an upper panel 12 of a first sound absorbing material comprising a first density and configured for placing on top of a base 14, the upper panel comprises a pair of end surfaces 16, 18 wherein one end surface of one panel of the plurality of sound absorbing panels is disposed adjacent to an adjoining end surface of another panel of the plurality of sound absorbing panels (figure 9c) ; at least one channel 20 disposed on a bottom surface forming at least one cavity when the upper panel is placed on top of the base, wherein the at least one cavity provides communication from one of the pair of end surfaces to another of the pair of end surfaces; and a second sound absorbing material of a second density disposed in the at least one cavity, wherein the second density is less than the first density.
