But as the roar of internal combustion engines fades, a new challenge&nbsp;emerges: the intrinsic quietness of Electric Drive Units (EDUs) brings the subtle sounds and vibrations of other components, especially the&nbsp;geartrain, into sharp focus. For automotive engineers, this means NVH (Noise, Vibration, and Harshness) performance is more critical than ever.&nbsp;<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-video\"><video controls src=\"https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/6\/2026\/02\/Housing.mp4\"><\/video><\/figure>\n<\/div>\n<\/div>\n\n\n\n<p>In the fiercely competitive EV market, OEMs and TIER1 suppliers are under immense pressure to innovate rapidly.
