This report discusses the technology and costs required to reduce the noise of a General Motors Brigadier heavy-duty diesel truck from 81.7 to 71.6 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 vehicle weight by 340 lb and estimated vehicle price by $1174. Wind tunnel tests on the completed truck show that temperatures of engine coolant and oil remain within manufacturer's specified limits.
