| Abstract |
This report discusses the technology and costs required to reduce the noise of an International Harvester F-4370 heavy-duty diesel truck from 81.1 to 72.2 dBA. The noise control treatment consists primarily of a dual exhaust silencing system and a partial enclosure for the engine and transmission. The noise treatment increases the vehicle weight by 332 lb and estimated vehicle price by $1302. Wind tunnel tests on the completed truck show that temperatures of engine coolant and oil remain within generally acceptable limits. |
