Abstract
Today several international brake acceptance tests exist, like the Los Angeles City Traffic test (LACT) or the Mojacar Noise Route in Spain. During these tests noise evaluation is done subjectively by test drivers, which can cause discrepancies. Sometimes noise data are recorded and evaluated by different, mostly company-specific methods but a procedure that considers the human perception of brake squeal is missing. To fill this gap, the procedure BONI (Brake Objective Noise Index) detailed in this paper is developed based on subjective ratings acquired in hearing tests. It provides reliable prediction of squeal annoyance with high correlation to human perception.
