With the rising need and demand for improved NVH levels in vehicles, the usage of NVH materials is increasing and becoming more relevant in the automotive industry today. NVH materials play a vital role in providing an engineered automotive sound package solutions to create an enhanced vehicle cabin experience for the users. This paper outlines a unique noise control treatment product which is designed and developed using specialized materials and process to enhance noise reduction inside vehicle cabin. The Integrated absorptive barrier is an advanced noise control treatment which is made using sustainable, environmentally friendly materials focusing on Green Chemistry principals and relatively less contaminating manufacturing process.

NVH in automobile has been very demanding over the years and is considered to be one of the key focus areas for customer satisfaction identified by the automobile companies. A lot of work has been done towards optimizing noise treatment materials and its effective placement to suit performance, weight and cost. This paper outlines a unique method to optimize the coverage of the NCT around the FOD area by conducting an effective sound intensity mapping around the FOD area at the cabin side with the help of a two microphone based sound intensity probe.
