• Abstract:
  A series of tests to measure the noise contributions of subsystems were performed on a truck with a conventional short cab, equipped with a Cummins V-903 engine. The data acquired in these tests were used to select retrofittable components which would effectively reduce the total vehicle noise. The final truck had the original induction system, a new single vertical late model muffler, a clutched fan drive and engine covers. All of the retrofitted components are commercially available and in stock. The total cost of all three changes is between $1000 and $1445 for a 3 dBA noise reduction. A 2 dBA noise reduction could be attained with engine covers only at a cost of from $470 to $770.
