The noise of the truck had been reduced from 81.1 d]IA to 72.7 dBA. _le truck accumulated 36,000 miles in 5 months of service. The treatments were effective and durable, and the noise level of the truck dld not increase. The treatments did not have an adverse impact on vehicle operations and there was no evidence that the welght of the treatments displaced payload. The treatments did not have a measurable effect on fuel consumption. The treatments had a minlmal impact on maintenance time. 117, KEY WORDS AND DOCUMENT ANALYSIS I DE,BCRIPTORS b.

PREFACE This report deals with the field testing by Bolt Beranek and Newman Inc. (BBN) of a quieted International Harvester F-4370 heavy-duty diesel truck, one of the heavy-duty diesel trucks in the Environmental Protection Agency's Demonstration Truck Pro- gram. The objective of this program, begun in 1979, was to demonstrate noise reduction technology for heavy-duty diesel trucks. The program included four trucks, each with a different engine. The original program plan called for each vehicle to receive noise reduction treatments and then to enter fleet ser- vice for a year of field testing. Each of the four vehicles successfully completed the noise reduction part of the program. The duration of the program was shortened from the original plan, preventing all four vehicles from completing a full year of fleet service. The International Harvester truck completed five months of field service before the end of the program in late 1981. Seven final technical reports and a program summary were prepared by BBN for the Demonstration Truck Program. Their titles are listed on the inside cover of this report. Each report is intended to be internally complete; therefore some redundancy occurs between the technology and cost reports and the field test reports. For example, a reader who has read the tech- nology and cost report for a particular truck will find that he can pass over Sec. 2 of the companion field test report for that vehicle. The authors are grateful to the many governmental and indus- trial organizations and personnel who have contributed to the development of this truck. The program has been sponsored by the Environmental Protection Agency's office of Noise Abatement and Control. The International Harvester Company provided technical information on the truck. The Cummins Engine Company performed iii Report No, 4797 Bolt Deranek and Newman Inc.
