Anyone who has worked in the automotive industry is likely to be familiar with the acronym NVH which stands for Noise, Vibration & Harshness—a term referring to the general objective of designing cars that run quieter and smoother resulting in a higher quality, more reliable product. Concern with NVH issues goes well beyond the automotive industry to almost every type of part, device or structure, and has become a general concern of most product designers today.
This article is a general discussion on the topic of noise and vibration control and analysis techniques from the perspective of someone who has worked as a consultant in this field of study for many years. At Boyd, we strive to bring this consultative, problem solving approach to how we support our customers’ issues utilizing a systematic and analytical thought process to understand the governing dynamics of a problem in order to best recommend the most appropriate countermeasures.
For some extreme cases, the NVH issue can result in an operating malfunction or mechanical failure of the device. Often times, however, the NVH concern relates to a perceived quality issue.
Boyd’s Discussion of Noise and Vibration Analysis and Control is written by a mechanical engineer with over 25 years of experience working in the area of noise and vibration control, both as a consulting engineer assisting customers to find solutions to their challenging NVH issues, as well as in support of product development of noise and vibration counter measures. His particular area of expertise is in the design of material-based damping treatments utilizing visco-elastic materials.
