Abstract (en)
[origin: EP1362963A2] The invention is a new soundproofing panel made of composite material, suitable for installation along railways and/or roads, comprising a box structure whose side facing the source of the noise is covered with suitably-spaced staves. The new soundproofing panel comprises an FRP box structure (S1, S2), a layer of sound-absorbing material (F), spacers (D), and parallel staves with an arched T-shaped cross-section; these staves (T) are preferably arranged alternately, i.e. so that each stave (T) has its cross-section inverted with respect to the two staves (T) on either side. <IMAGE>
