The handbook has been prepared with the intention of assisting the truck fleet operator and the independent truck owner/operator in understanding and diagnosing noise problems and in selecting retrofittable components to lower truck exterior and interior noise levels. The handbook includes procedures for identifying and evaluating major truck noise sources,considerations for selection of acoustic materials,procedures for minimizing exhaust,intake and cooling fan noise,and methods for the minimization of in-cab noise levels. Appendixes give standard noise measurement procedures,muffler and intake filter selection data,cooling system design considerations and a list of known manufacturers of acoustic materials.
