Noise, vibration controls white paper directed at control engineers

The four principal tools for noise and vibration control (damping, isolation, absorption, and barrier materials) are the focus of a white paper from E-A-R Specialty Composites.


The four principal tools for noise and vibration control (damping, isolation, absorption, and barrier materials) are the focus of a white paper from E-A-R Specialty Composites . Directed at control engineers, the tutorial, titled “The Four-Fold Method of Noise and Vibration Control,” is said to give control engineers a better understanding of how passive acoustical systems can best be used to improve instrument designs at low cost.

“Whether control engineers are attempting to retrofit noise and vibration controls into existing products, or considering new instrument designs, it pays to have a better handle on basic principles that affect choices of materials for noise or vibration controls, said George Gabuzda, senior director of E-A-R. “Choosing the right materials for a particular noise or vibration problems does not require magic, but can sometimes be tricky.”

E-A-R manufactures proprietary, high-performance plastics and foams—vinyls, urethanes, and rubbers—for noise control, vibration isolation and damping, cushioning, and ergonomics. The 8-page paper is free. Click here to download a copy .
