TRUCK NOISE X: NOISE REDUCTION OPTIONS FOR DIESEL POWERED INTERNATIONAL HARVESTER TRUCKS. VOLUME II. COST-NOISE ANALYSIS AND FIELD INSTALLATION
Noise reduction option development work was carried out on two inservice diesel powered IH trucks, consisting of a Cab-over model and a Conventional model with a baseline exterior noise level of 87 dB(A) each. Since no specific noise goals were set, International Harvester established an exterior noise reduction goal of 83 dB(A). Then, for each vehicle, proper noise source identification techniques were applied and major contributors were established. The commercially available source noise reducing components were tested singly, and were selected based upon an optimum evaluation. The selected components were collectively installed on the trucks and cumulative performance in the total truck environment was found to be adequate to meet the established noise level goals.
