Abstract

Designing for NVH (Noise, Vibration, and Harshness) is a process that requires the integration of customer product expectations with the vehicle design and development process. To the customer, NVH is defined in terms of how the vehicle “feels” with regards to vibration levels at the seat, toe pan, and steering column, and how the vehicle “sounds” with regards to the perceived loudness and quality of the interior noise. To design and development engineers, NVH is defined in terms of measurable tactile and acoustic responses.

The following sections of this paper will describe the conversion of the subjective customer expectations to objective measures which can be arrived at through vehicle system NVH simulation and testing. In addition, the process of establishing vehicle and subsystem design targets will be covered along with some basic principles of designing for NVH.
