TRUCK NOISE III-C. SOURCE ANALYSIS AND EXPERIMENTS WITH NOISE CONTROL TREATMENTS APPLIED TO FREIGHTLINER QUIETED TRUCK

The report describes the diagnostic tests and noise treatments developed to attenuate the noise of a Freightliner cab-over-engine (COE) diesel truck. In the course of the program, we measured the contributions of major truck components to the overall radiated noise level and applied appropriate noise control treatments. The program succeeded in reducing overall truck noise from 88 dB(A) to 72 dB(A).
