Automotive OEM Barrier Acoustical Performance – the Ideal Application for Carbon Neutral Materials 2023-01-1049

The Automotive acoustics arena is rich with application opportunities for carbon neutral or climate positive parts. Designing possible “green” NVH solutions however must never compromise the intended acoustical performance of the vehicles. This paper investigates the acoustical needs of OEM vehicles with an emphasis on applying green solutions. These acoustic solutions proposed will compare and contrast barrier densities, flex modulus, weldability, flammability, sealing characteristics as well as Mass Law calculations between traditional and carbon neutral acoustical barriers. Furthermore, these measures will demonstrate that vehicular acoustic performance need not be compromised as the industry moves down the road towards more climate friendly initiatives. We intend to provide actual OEM vehicular test results measured using traditional and carbon neutral barrier solutions. Lastly, the paper will identify what the writers consider to be ideal applications for planet friendly, carbon neutral NVH solutions using acoustical barrier applications specifically, that are production ready and commercially available today.
