This paper describes the use of a drag type (also included some brake stops simulations) noise dynamometer to validate brake squeal performance. The problems of correlating objective dynamometer measurement to subjective in-vehicle measurement are discussed. One of these, the perception of the human ear to sound is examined and the application of psychoacoustics to brake squeal is examined and applied using a practical example. A proposal for future work is outlined.
