Sound Levels of Highway Truck Tires, Proposed SAE Recommended Practice XJ57

A noise standard is acceptable only if it isolates the area of concern (tire sounds), correlates to human response, and is repeatable, easily understood, and economically feasible. With these goals attained, the SAE Subcommittee on Truck Tire Noise proposes their recommendations on “Sound Level of Highway Truck Tires-Recommended Practice SAE XJ57.”

Part I of this paper contains the final draft of the test procedure that the Subcommittee has proposed to SAE committees as a recommendation. Part II explains and supports the Subcommittee's decisions for the recommended specification.
