This report discusses the technology and costs required to reduce the noise of a Ford CLT 9000 heavy-duty diesel truck from 77.1 to 72.3 dBA. The noise control treatment consists primarily of a dual exhaust silencing system and a partial enclosure for the engine and transmission. Wind tunnel tests on the completed truck show that temperatures of engine coolant and oil remain within manufacturer's specified limits. The noise treatment increases the vehicle weight by 397 lb and estimated vehicle price by $1309.
