Noise and vibration analysis is becoming increasingly important in virtually every industry. The need to reduce noise and vibration can arise because of government legislation, new lightweight constructions, use of lower cost materials, detectability, fatigue failure or increased competitive pressure. Wave6 is used in a wide range of industries to evaluate noise and vibration performance during the design stage in order to reduce the risk of discovering expensive problems late in the design cycle when physical prototypes become available
