Knowledge Discovery tools for vehicle noise and vibration reduction

In the automotive industry, the product engineering must follow and analyze a series of information concerning characteristics of the vehicles. The area of called knowledge NVH (noise, vibration, harshness) is responsible for the acoustic comfort that this vehicle provides. Great volumes of information are stored in analyzed computers and so that possible acoustic problems are found by the product engineers. The present article has covered the relations and characteristics of this subject having considered that this process of acquisition and deriving data handling of Tests of NVH can be sped and be improved with the application of the KDD tool (Knowledge Discovery in Databases).
