Tutorial Explains Noise and Vibration Control

Designers of precision electronic equipment seeking to build cost-effective noise and vibration controls into their product designs can obtain a systematic and concise tutorial authored by E-A-R Specialty Composites (E-A-R). The tutorial outlines the four principal tools for noise and vibration control (damping, isolation, absorption and barrier materials). The white paper, “The Four-Fold Method of Noise and Vibration Control,” was developed to help electronic products designers get a better understanding of how passive acoustical systems can best be used to improve product designs at the lowest cost.

George Gabuzda, senior director of E-A-R, comments, “Whether design engineers are attempting to retrofit noise and vibration controls into existing products, or considering new product designs, it pays to have a better handle on basic principles that affect choices of materials for noise or vibration controls. Because E-A-R manufactures a broad selection of materials for noise and vibration controls, the company usually can offer electronics products designers a wider selection of choices for noise and vibration controls.

Choosing the right materials for a particular noise or vibration problem does not require magic, but can sometimes be tricky. Through many years of partnering with precision electronics manufacturers to solve noise and vibration problems, E-A-R’s engineers know both the usual noise sources in electronic product designs, and how to efficiently diagnose the specific acoustic signature of a particular model. “The Four-Fold Method of Noise and Vibration Control” tutorial is available at www.earsc.com/pdfs/engineering/4foldWP.pdf.
