Summary:

Gear whine is a fundamental issue associated with the design of automotive transmission gears. The evaluation of gear whine has long been a subjective rating. The goal of this paper is a comparison of the objective data and the subjective rating system. Objective analysis can not always replace the subjective evaluation completely, but it can induce a consistency that subjective rating lacks. An objective analysis method of in-vehicle gear whine order tracked data subtracted from the overall noise level over a rpm range is compared to subjective rankings to establish an objective rating. A correlation and statistical analysis of the objective data has proven effective in evaluating the noise performance of gear whine in a vehicle. There is a concern for the acoustic performance of the gears in a transmission and a consistency in the evaluation, due to the ever increasing customer awareness of noises in automobiles
