Title: New Concepts for Acoustic Material Selection
text: Significant developments in moldable noise reduction materials will allow design engineers of off-highway equipment to incorporate molded parts concepts into their design schemes for both the cab and engine compartments as their use of contoured shapes continues to increase. When properly designed, and used in conjunction with complementary treatments which have been carefully selected on the basis of proven acoustic test criteria, molded sound barriers and sound absorption parts are more cost effective than the oft seen overkill of conventional materials.
