Abstract
A test method for accurately determining the noise levels of truck cooling fans, as a function of their performance, has been developed. Correlation between the calculated results, using this test method, and experimental results of tests with a simulated truck cooling system environment has been demonstrated. Since fan noise is a major component noise source for trucks, this procedure is of particular interest to engineers involved in meeting legislated vehicle noise levels.
