The U.S. Department of Transportation in a study of truck noise emission standards found that the proposed standards of 83 and 80 dBA for new medium and heavy duty trucks would effect savings of 45.2 and 18.7 billion dollars, respectively. The standards would be technologically available within model year 1977 through 1980. The proposed 75 dBA for model year 1983, however, was not found to be justified, since incurred costs of 9.1 billion dollars could not be justified in terms of benefits derived. Cumulative fuel savings for each regulatory strategy were calculated from predicted sales. In the case of the 83 dBA noise standard, for instance, fuel savings would total 530 million gallons for 400,000 new trucks through use of a cooling fan control. The costs of complying with the standards were calculated for a new heavy duty diesel truck and then compared with estimates made by truck manufacturers. To meet the 83 dBA standards DOT estimated a cost of 329 dollars, compared to 385 dollars estimated by the Ford Motor Co., 365 dollars by General Motors, and 195 dollars by EPA. For an 80 dBA standard, DOT estimated 1,076 dollars, compared to 1,090 dollars by General Motors, and 487 dollars by EPA. The DOT estimate for a 75 dBA standard was 1,075 dollars, compared to 4,450 dollars by General Motors, and 1,119 dollars by EPA. Community noise level reductions were predicted for four regulatory strategies. It was noted that a total reduction of 7.72 dBA would be effected in urban street traffic noise by the year 2000 if only rib tires were used.
