Abstract: Vehicle noise, vibration and harshness (NVH) is an important vehicle attribute. It is usually among the top five attributes in terms of its priority in the design of any vehicle type. Like other attributes of safety, performance, dynamics and fuel economy, this attribute has to be considered closely in the design process. This manuscript presents an overview of automotive NVH engineering. It classifies the interior noise into powertrain-related NVH, road- and tyre-related NVH and wind-related NVH. This paper also discusses brake- and chassis-related NVH, squeak and rattle and electromechanical-related NVH. In addition, the paper addresses exterior NVH, frequently described as drive-by NVH. The phenomenon is divided into usual or expected NVH and unusual or unexpected NVH. The paper provides a review of some of the recent literature in the field of automotive NVH.

Keywords: air-borne noise; automotive VNH; fluid-borne noise; vehicle noise; operating conditions; research; root-cause; structure-borne noise; unusual NVH; usual NVH; vehicle vibration; harshness.
