It is important to understand not only the noise problem, and the functional and aesthetic issues of an automobile, but also the environmental and competitive issues of the industry to develop appropriate sound packages that will meet the customer requirements. The vehicle manufacturers and their suppliers do so within the bounds of the material and process development technology that is available. The evolution of the basic automobile design and construction also has a significant impact on the sound package development. This may require an entirely new type of material application or an innovative process and product. The paper reviews different types of sound package and process developments that have evolved over the years in some specific applications. These developments not only provide balanced acoustics inside the automobile, but also meet various challenges of the industry.
