摘要：从一次研讨会的有些笔记关于AME出席了被提出的声波测距。随着涡轮喷气的出现供给动力的运输航空器，盘区振动变得重要在喷气机尾气期间，它是，结合与高频率刀片段落，并且一每rav短管轴自转是新的事。

摘要： 从声音测量研讨会 AME 出席了一些笔记列示。随着涡轮喷气发动机动力运输飞机的出现，面板振动变得非常重要它已经在喷射排气，加上高频率的叶片通道期间，燃起一每丝线轴轮换了新的东西。声学工程师测量了测试部分的声音传输特性 ；他们在切在厚厚的墙分离公司的混响室窗体中，anecholic 分庭孔径安装了测试板。AME 决定使用该公司购买的压电加速度计的一对。这是一个新的概念在感测器 ；以前单位一直重量约四分之一磅的线圈和磁铁设备。
