Noise Vibration Harshness (NVH)
 |
In a critically competitive market, passenger comfort is an important customer acceptability criterion. Our NVH engineering team helps customers to identify comfort and noise problems in early design stage or in trouble-shooting situations, where a practical solution must be provided in short time. CDH provides measures to optimize ride comfort and interior noise fulfilling customers comfort, cost and weight targets.
