Keys to Successful Engine NVH Testing

From Sciemetric Instruments

Many factors are driving the need for automotive manufacturers to implement more stringent noise, vibration and harshness (NVH) testing. Consumer tolerance for any perceived noise is minimal. The slightest unexpected engine noise can lead to a costly warranty claim. Other factors such as longer warranty periods and increasing engine complexity compound the NVH challenge for manufacturers. These manufacturers must earn customer satisfaction and minimize the risk of a large warranty exposure by implementing systems to drastically reduce engine NVH defects.
