This report describes a cooperative program sponsored by TRRL which has produced heavy diesel engined articulated vehicles having considerably lower external and internal noise levels than vehicles in current operation. The work was aimed at reducing the noise levels from the engine, exhaust and cooling systems and tire-road surface interaction. Results are given from a number of experimental vehicle builds and a demonstration vehicle built to production standards, which emitted no more than 80 dB(A), is described.
