TRUCK NOISE VIII: THE DETERMINATION OF THE PRACTICAL NOISE CONTROL RETROFITTING OF PRE-1970 TRUCK AND COACH MODELS

A retrofit noise package was selected for four representative GMC vehicles; i.e., two Heavy Duty Conventionals, one cab-over engine Heavy Duty Astro, and one 53 passenger transit coach, to achieve optimum noise reduction. The selection of this material came from commercially available items submitted by various component suppliers. A new system of noise-source isolation was developed in order to evaluate the vendor-supplied material. The best one of these components was then selected for the final Retrofit Noise Package.
