The exterior and interior noise level of passenger cars has been reduced in the past to a large extent by legislation and on the demand of the car purchasers. One important marketing aspect today is the possibility to enjoy driving, which is determined by the noise quality and not the noise level inside passenger cars. However the interior noise quality of today's passenger cars does not always satisfy the people affected. In the development process of a vehicle, the noise quality is determined on a subjective basis by test drivers. A great deal of experience and time is required for the subjective assessment and for the further definition of strategies and their application to meet sound engineering targets for noise quality. This paper reports on the result of a R&D program to develop a software based Noise Quality Map with which the interior noise quality of passenger cars can be determined on an objective basis by measurement in real-time.
