Today, driving comfort is related to the absence of annoying noise. Therefore, the elimination of noises like squeaking, rattling and rubbing is a very important part of the whole value-added chain in the automotive industry — starting from the idea up to the quality product. For this reason, the measurement system SBS (Systematik zur Beseitigung von Störgeräuschen) from Ziegler Instruments can make a contribution. For example, whenever the rattling of the seat-belt retractor irritates a customer, he will complain about this. The costs of the resulting warranty repair and not least the loss of image for this particular car model are not acceptable for any company in a time of continuous improvement. © Springer Fachmedien Wiesbaden 2001.
