This report describes the field test and operational performance evaluation of a quieted Ford CLT 9000 heavy-duty diesel truck. The noise of the truck had been reduced from 77.1 dBA to 72.3 dBA. The field test showed the noise control treatments to be effective and durable in over 100,000 miles of service. The treatments had no adverse impact on the vehicle's operation and appear to have had negligible effect on fuel consumption. Incremental maintenance time of 2.5 hours was attributable to the treatments' impact on normal annual vehicle maintenance.
