Methods Use the calibration module of system, configure the system with manikin made of aluminum or copper plate and arrange dynamic noisecurve.
方法借助系统自集成的定标模块，用铝或铜板模拟人体对系统进行定标配准；同时整理动态噪声分布曲线。

The wheel web, by virtue of its geometry and material characteristics, is a good emitter of high-frequency sound, and is believed to be the primary source of curve squeal noise.
尺寸和材料的特性导致了轮辋是一个良好的高频声源，轮辋也被认为是曲线尖啸噪声的主要来源。
