Determining Magnitudes of Axle Gear Noise 630166

A simple and basic laboratory test is described which may be used to evaluate and compare axle noises in a passenger car. In this method, a number is assigned to the magnitude of a given noise at any given frequency through a complete range of speed and load conditions during typical vehicle operation. A chassis dynamometer is used to simulate road conditions, and various pickup and recording instrumentation are employed to record the objectionable noises under different operating conditions and speeds.
