Abstract
Vibration and noise amelioration in and across several components and modules of the automotive, such as the panels, doors, engine covers, seats and others, is extremely important. NVH performance has been recognized as a critical factor in the purchase decisions of many buyers. This study examines the vibro-acoustic characteristics of some monolithic and composite materials and some generally periodic material structures. By experimental and numerical/empirical methods, it explores some opportunities for minimizing the transmission of noise and vibration. Some new constructions not hitherto probed for vibro-acoustic fitness are examined. Results from this study are expected to contribute towards design inputs to obtain better performances.
