INDIANAPOLIS, In. — Truck designers seeking to build noise and vibration controls into their product designs can now obtain a tutorial outlining how control noise and vibration control.

The tutorial, which addresses four tools for noise and vibration reduction, namely damping, isolation, absorption and barrier materials, is available courtesy of E-A-R Specialty Composites (E-A-R).

The company specializes in composite/elastomer engineering and product development for handling noise, vibration, comfort, thermal requirements and/or shock.

"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, say company officials.

"Whether automotive engineers are attempting to retrofit noise and vibration controls into existing models, 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,” says E-A-R Senior Director George Gabuzda.

“Because E-A-R manufactures the broadest selection of materials for noise and vibration controls available from a single source, we usually can offer product designers and engineers a wider selection of choices for noise and vibration controls than is expected. Choosing the right materials for a particular noise or vibration problem does not require magic, but can sometimes be tricky.”

The tutorial is eight pages long and is available at www.earsc.com/pdfs/engineering/4foldWP.pdf, or by writing to solutions@earsc.com, or phoning 1(877)3274332.
