The paper describes a project that is developing a quiet, heavy demonstration vehicle. The vehicles are due to be available after about three years, and are intended to be at least 10dB quieter than current vehicles under the normal test conditions and under normal operating conditions. An estimate is included of the effects on the overall noise climate of the use of heavy vehicles quietened to this level.
