The ability to utilize existing infrastructure i.e. tools, equipment and machinery to generate a unique acoustic product offering with minimal changes is important. This is because no generic acoustic solution ( material or composite ) exists for different vehicle configurations. Also, recent developments in predictive acoustic engineering and enhanced CAE capabilities as applied to development of optimal flat sample criteria for in-vehicle transmission loss and absorption performance allow for reverse engineering of the noise control systems. This reverse engineering coupled with a flexible manufacturing system will allow customization or tuning for any given program. Cost effective acoustic systems that can provide optimal insertion loss/absorption ratios utilizing a common manufacturing process will be the enabler to sustain competitive advantage.
