The principle relies on a piston mechanically driven to move at a specified cyclic rate, pushing on a fixed volume of air to which the microphone under test is coupled. The air is assumed to be compressed adiabatically and the sound pressure level in the chamber can, potentially, be calculated from inte… parkview occ health fort wayne inWeb声级计. 声级计的校准根据IEC 61672，BS 7580，ANSI S1 4和ANSI S1.43标准进行。. 程序中包括公差并旨在验证声级计的特性是否正确。. 测试内容如下：麦克风和滤波器的频率响应、时间权重（快、慢等）、电平线性、超范围指示等。. 声级计分为不同的精度等级，其中1 ... parkview occupational health clinicWeb1" Microphone with preamplifier Pistonphone ., 1/2" Microph one wit h preamplifier Pistonphone -~, iiiliiiiil··-----tF~ b) 740366/ 1 Fig. 2.
