Abstract
This report describes the field test and operational performance evaluation of a quieted General Motors Brigadier heavy-duty diesel truck. The noise of the truck had been reduced from 81.7 dBA to 71.6 dBA. The 12-month field test showed the noise control treatments to be effective and durable, although the noise level of the truck did increase slightly. The treatments did not have an adverse impact on vehicle operation and there was no evidence of payload displacement. The vehicle's fuel economy was better than that of comparison vehicles, but this was not caused by the noise treatments. Incremental maintenance time of 2.25 hours was attributable to treatment removal and interference while performing regular maintenance during the 12-month period.
