Wired for sound


 
A lightweight audio system integrated into a car’s interior roof could soon render loudspeaker units in door modules or instrument panels obsolete, while the headliner itself is likely to be of hemp, flax, kenaf and sisal nonwovens and soy foam as a replacement for fibreglass fabrics.
The new audio concept has been introduced at 2011 car shows by Johnson Controls, which is now the leading supplier of automotive fabrics worldwide.
In its ie:3 demonstrator car,  the headliners and trim become loudspeakers, and a digital signal processor (DSP) maximizes the audio performance, while LED lighting in tune with the acoustics creates a relaxing interior ambience.
