Summary

The Headliners, Soft Trim and Acoustics report covers trends in two related areas of the car, namely: headliners and related trim parts which increasing play an acoustic function in the car and the wider issue of vehicle acoustics and NVH materials.

It specifically looks at how car companies have integrated the development of an acoustic and NVH (Noise, Vibration and Harshness) strategy into new vehicles' engineering programmes from the outset, rather than simply adding acoustic materials to vehicles when they are close to the start of series production. Moreover, one of the key themes of this report is how the industry is increasingly designing acoustic functions into interior and indeed exterior parts. In turn, this has significant consequences for suppliers of both traditional NVH or acoustic materials and the components which use these materials.

This report is over 100 pages in length and includes key profiles of all the major suppliers in this sector.
