高声级传声器，外部极化
4941型高声压传声器专为在4Hz至20kHz的频率范围内进行枪声、烟花和火箭等极高声级测量而设计。
4941 系列
这款压力场传声器的坚固构造使其能够承受高达 201 dB 的瞬态压力而不受损害。由于外部极化，4941 型必须与经典的前置放大器一起使用。

The unit is assembled in a clean-room environment and sealed together, after which it is assigned one single type number and one single serial number. This means that the combined unit has better precision and long-time stability, and is handled as one complete unit.
The unit also contains TEDS, which means that information about the serial number, type and sensitivity is stored within it.
