Abstract
In an effort to further reduce noise inside the passenger compartment of automobiles, a new approach has been made to incorporate parts not traditionally considered to be acoustic in nature. Through use of patented technology, the acoustic improvement can even be tuned to specific audible ranges to quiet background noise and improve audio clarity for devices such as hands free cellular phone devices. This paper will discuss the theory of using perforations for acoustic applications, demonstrate how the acoustic response can be tuned with flat sample development and illustrate actual invehicle data showing potential improvement of perforated plastic components.
