Abstract
In most brake development projects, brake noise is judged by a
combination of subjective rating evaluations done by skilled
drivers and statistical methodologies obtained from different brake
durability studies. Drivers are the most important factor for the
final judgment, and therefore they have to be trained to
distinguish different kinds of low, medium and high frequency
noise. Sometimes this is not easy, and evaluations may differ
depending on the driver's criteria.
This document summarizes the development by IDIADA's brake
engineers of an automated acquisition and data processing system
which is called dbbrake for the full characterization of all the
ranges of brake noise which appear in a brake durability test.
