This report describes the field test and operational performance evaluation of a quieted International Harvester F-4370 heavy-duty diesel truck. The noise of the truck has been reduced from 81.1 dBA to 72.7 dBA. The truck accumulated 36,000 miles in 5 months of service. The treatments were effective and durable, and the noise level of the truck did not increase. The treatments did not have an adverse impact on vehicle operations and there was no evidence that the weight of the treatments displaced payload. The treatments did not have a measurable effect on fuel consumption. The treatments had a minimal impact on maintenance time.
