GB/T 15528-2013 Methods of measurement on microphones and earphones for speech communications

Scope

This standard specifies the measurement methods for microphones and headphones used in voice communication.
This standard applies to the microphone and headphone parts of handheld headset-microphone sets, head-worn headset-microphone sets, or headphone-microphone sets, as well as to the microphone units and headphone units integrated into handheld headset-microphone sets, head-worn headset-microphone sets, or headphone-microphone sets.
The purpose of this standard is to establish definitions related to these electroacoustic transducers and to standardize the required characteristics and related measurement methods. The use of other measurement methods that can yield the same results is not excluded. The detailed methods used should be provided together with the measurement results.
