Growing customer expectations increasingly push for noise-reduced cars. Therefore, OEMs continuously struggle to identify and reduce noise sources. Also, the increasing pressure for fast prototyping and shorter “time-to-market” calls for improved and more efficient noise, vibration and harshness (NVH) test methods. Generating reliable data is critical in this process, and it requires using the best measurement microphones as well as constantly improving the measurement procedures.
随着客户的要求越来越高, 越来越多的降噪汽车推 出市面。因此，代工生产不断努力识别和减少噪声源。此外，市场步伐越来越快，原型制造的速 度压力越来越大，“推出市面的时间”越来越短， 市场需要更完善且更有效的噪声、振动和粗糙度 （NVH）的测试方法。产生可靠的数据是在NVH测 试过程中最关键的。要达到理想效果，您需要使 用到最佳的测量麦克风并不断地对测量程序作出 改进。这就是为什么GRAS研发出一种针对冷、 热发动机测量进行优化的新型表面麦克风。
This is why GRAS has developed a new surface microphone optimized for cold and hot engine measurements. 这就是为什么GRAS研发出一种针对冷、 热发动机测量进行优化的新型表面麦克风。
