Volke improves the noise comfort of an automobile.  Extensive noise and vibration measurements on the entire vehicle, in the street, or on a roller dynamometer provide information about engine-, chassis-, and wind noises.  Using the most modern measuring equipment, Volke documents complaints and their remedies, and carries out modification A-/ B-comparisons.  And because, in addition to our own in-house acoustic measurement labs, almost all of our measurement systems are mobile, making it possible to carry out a large proportion of our testing at our customers' locations.
