标准范围

IEC TR 61904-10:2022-适用于符合IEC 61094-1要求的实验室标准传声器和其他类型的测量传声器，-描述了用于基于能够产生已知声压(尤其是在低频下)的装置来确定复数压力灵敏度的一种可能的绝对方法，以及-为低频下的声压测量提供可重复且准确的基础。所有量均以SI单位表示。

IEC TR 61904-10:2022
- is applicable to laboratory standard microphones meeting the requirements of IEC 61094-1 and other types of measurement microphones,
- describes one possible absolute method for determining the complex pressure sensitivity, based on a device capable of generating a known sound pressure, especially at low frequencies, and
- provides a reproducible and accurate basis for the measurement of sound pressure at low frequencies.
All quantities are expressed in SI units.
