INDIANAPOLIS, Ind. (May 20, 2005) — Damping; isolation; absorption; barrier materials: Those are the four tools of noise and vibration control for commercial trucks, says a whitepaper authored by E-A-R Specialty Composites.

The company — a world leader in composite/elastomer engineering and product development for handling noise, vibration, comfort, thermal requirements and shock — says its report provides truck designers a systematic and concise tutorial on how to build cost-effective noise and vibration controls into their products.

The whitepaper, titled The Four-Fold Method of Noise and
Vibration Control, white paper will help truck designers get a better
understanding of how passive acoustical systems can best be used to improve product designs at the lowest cost.

“Choosing the right materials for a particular noise or vibration problem does not require magic,” says George Gabuzda, senior director of E-A-R, “but can sometimes be tricky.”

Through many years of partnering with truck manufacturers to solve noise and vibration problems, E-A-R’s engineers know both the usual noise sources in truck designs, and how to efficiently diagnose the specific acoustic signature of a particular model.” Gabuzda says.
