NVH – Noise Vibration & Harshness
An extensive subject matter covering all aspects of the study of noise and vibration in vehicles. This used to be very much focused on cars and trucks, although its application is more widespread these days. It is still centred on the acoustic and vibratory responses within vehicle structures and how these impact the driver experience as well as affect the long term reliability of the vehicle itself. We all want a quiet, smooth and refined drive and don’t want to be bouncing and vibrating our way down the highway. It is the world of NVH – Noise Vibration & Harshness to ensure this is under control.
The field also now covers new aspects such as the active addition of noise into areas such as exhaust sound and how to make electric vehicles noisier to make then safer for pedestrians. It is an ever evolving field making it a fascinating engineering challenge.
