嗡嗡吱吱嘎嘎异响（BSR）
对新产品品质评价属性的最差前几名中，BSR就占据一席。VA One2010.5版本包括了能够有效预测结构处于低频随机噪声及振动环境中BSR异响的独特功能。新的功能对于所有VA One用户开放。借此，用户可以改善产品品质并且减少由于产品缺陷导致的召回产品带来的损失。

气动噪声(Aero-Vibro-Acoustic)
准确描述由于结构外表面空气流动产生的内部噪声是一个富有挑战性的任务。VA One2010.5版，借助使用CFD计算或风洞测试的数据，模拟复杂扰动表面压力载荷的方法使上面的问题得以简化。这种方法适用于描述低频、中频以及高频的复杂声源。VA One2010.5也包含了使用边界元和快速多级边界元方法模拟外部流动噪声辐射和散射的空气声功能。

VAONE也开始进行气动噪声的计算了！呵呵！有点意思啊！
