Scope

This part of GB/T 12060 specifies the measurement methods for the electrical impedance, sensitivity, directivity pattern, dynamic range and external influence of acoustic system microphones. This standard applies to all sound system microphones used for speech and music. But for each audio channel with multi-channel microphones, such as stereo or similar. This section also applies to embedded microphones and microphones with analog characteristics of digital audio output. Microphones to which this section applies include all devices, such as transformers, preamplifiers or other components that form an integral part of the microphone, until the output specified by the manufacturer. This section does not apply to measuring microphones.
