Purpose

The acoustic requirements of automotive components have drastically increased in importance over the recent years due to legal regulations, lightweight design and higher customer demands. To shorten design phases it is necessary to evaluate the acoustic behavior already in the concept phase and/or in very early design phases using CAE methods. Especially the global dynamic characteristics of components are responsible for the acoustic performance, which only can be influenced significantly in the concept phase. Using MNOISE critical areas and acoustic hotspots can be detected on the virtual component by evaluating acoustic near field measures. Based on these results, design improvements can be done.
