声学和振动特性是影响车辆质量感知的关键因素。NVH（噪声、振动与声振粗糙度）的优化涉及对整车及其所有子系统（包括声学腔体）振动行为的深入理解。
IDIADA 在车辆 NVH（噪声、振动与声振粗糙度）性能优化方面拥有丰富的试验和仿真经验，深谙如何实现仿真结果与真实工况之间的高相关性。
通过将有限元模型与多体动力学模型相耦合，我们能够精准预测悬挂受力点的加速度或声压水平。将这些模型与 IDIADA 的虚拟试验场（Virtual Proving Ground）结合使用，即可在真实感受的环境中，对整车在研发过程中的响应行为进行完整评估。
NVH 领域还包括对其他系统的优化，例如刹车啸叫仿真、车内装饰件的吱吱声与松动声（squeak‑and‑rattle）以及侧镜的气动声学特性。
