The article discusses quieter methods of piling and reducing noise from mobile or stationary plant. Radical redesign of engines is needed to achieve reduction of more than 10 db(a); however, the author discusses various palliative measures being tried to reduce engine noise. He describes how a recently completed project sponsored by the building research establishment has reduced the noise of an articulated dumper by 10 db(a). Noise from stationary plant can be reduced by screening or commercially available acoustic sheds. Quieter methods of piling discussed include the development of the taywood pilemaster and the hush piling rig where individual hammer blows were measured at 80 db(a) at 7 M. The dawson drop hammer which uses a resilient cushion of rubber/rope laminate is described. Methods of avoiding sheet piling are examined and research into a quiet piling system is mentioned. /TRRL/
