Sound data were recorded from a series of trucks that were operated in various powertrain conditions. The acquired sounds from both the steady state engine speed and second gear wide open throttle operation were then presented to a group of subjects as paired comparisons. Correlation between these subjective ratings to the objective measures of the engine sound were then done and a linear relationship developed.
