Abstract
A porous plastics foam body 122 in a string net tube 125 is clamped over substantially its entire length between a resilient member 123 and the wall of the air passage 121. The member 23 may be a helical or zig-zag, Figs. 2A and 2B (not shown), wire spring or a further foam body or a rubber body. A pair of foam bodies (152, 154), Fig. 4 (not shown) may be clamped by a single helical spring (153). <IMAGE>
