Abstract
This paper reviews the evaluation of four Light vehicle exterior noise test procedures. Vehicle test results from two part throttle and one multi mode test are compared to the results from a currently in use wide open throttle procedure SAE J986.
Each procedure is evaluated for clarity of instructions, time to test requirements, equipment requirements, vehicle changes required for the test, sound levels produced, how the procedures rank vehicles and the sources of sound.
