常规声强探头
● 符合IEC 61043 class 1和ANSI SI.12
● 使用相位匹配传声器
● 用于声功率测量
● 可进行远程控制
● 噪声源级别判断
● 声强分布描绘
声强测量技巧是查找声源，排序次序和判断发放声功率的强大工具。方法原理是从两个相近的传声器同步判断出声压和粒子速度，声强探头一定要确保两个传声器之间有定义明确的空间和将声场干扰减低。若要得到zui准确的测试结果，传声器间的空间一定要优选，以配合实际测量情况。在低频和高回响的情况下，相距一定要远，当频率高时，距离则要近。
50AI具备多种不同间隔，有12mm到100mm传声器的坚固隔板可供选择。探头设计是仪器不用拆散，也可以改变其相隔距离。
有关声强传声器的相位反应：一般来说，声强测量是从不同位置的传声器分别收到声波的时间相差去量度声波方向。如声波先到达a传声器，然后b传声器，那么声波的方向一定是由a去b，如声波先入b传声器接收，那么声波方向便是由b去a。如a和b同时接收到声波，那么声波的移动方向便是跟a和b传声器成直角。传声器准确地判断细微时差的能力可称之为两个传声器之间的相位差。所以，对于声强传声器而言，相位配合是一非常重要元素。
50AI型包括一对1/2"40ai型声强传声器、定距柱、适配器、一对1/4"26aa型前置放大器和一只遥控手柄。该遥控手柄有多种不同款式供您选择以配合各种声强分析仪。其遥控功能使得数据采集过程可由计算机控制该手柄并自动完成。
● 50AI-B型：内置遥控设备，适用于许多第三方供货商的声强测量系统，可直接连接并控制
● 50AI-C型：使用标准的7针lemo接口与任何声强分析仪连接
● 50AI-D型：与b型类似，但是使用9v内置电池（交货时已提供）驱动其遥控设备
