TRUCK NOISE-IV G FIELD TEST RESULTS ON A HEAVY DUTY, DIESEL TRUCK HAVING REDUCED NOISE EMISSIONS

The report discusses truck noise as the complex interaction of many separate sources which have been identified and studied on an individual basis. This report describes the hardware used on four fleet test trucks, and analyzes the results of one year of actual service in a typical, general cargo carrying fleet. Two different types of vehicles were evaluated in the fleet test, the distinction being in the method used to reduce the engine noise. During the one year fleet test, each of the trucks accumulated approximately 150,000 miles of service in a common carrier fleet.
