Revision Standard - Active.
Practical methods for making electroacoustic laboratory measurements of analog and digital speech communications terminals and connected audio devices are contained in this standard. The methods are applicable to a wide variety of wired, wireless, cordless, and mobile communication terminals. Examples include Voice over Internet Protocol (VoIP), Wi-Fi®, and softphone devices. Tests applicable to connected audio devices such as wired, Bluetooth®, and universal serial bus (USB) handsets, headsets, and wearables are included. The standard contains objective metrics, subjective metrics, and subjective metric predictors. Application is in the frequency range from 20 Hz to 20 kHz.

This standard provides techniques for objective measurement of electroacoustic devices used for speech communications, including communication devices also used for multimedia applications. Application is for devices that are primarily used closely coupled to the ear. Aspects of devices with speakerphone or speaker listening features are covered by IEEE Std 1329(TM).
This standard is applicable to devices that include communication terminals that connect to a network, as well as to subsystems that connect to a terminal. The methods in this standard specifically apply to devices that connect to analog, digital, Voice over Internet Protocol (VoIP), and other local area network (LAN) networks. They may also apply to devices that connect to mobile and other wireless networks.
This standard applies to terminals independently of the internal audio architecture. Examples include cordless phones, VoIP phones, and softphone clients. It also applies to subsystems such as universal serial bus (USB) audio devices, Bluetooth(R) headsets, and four-wire analog handsets.
Due to the various characteristics of these devices and the environments in which they operate, not all of the test procedures in this standard are applicable to all types of terminals and subsystems. Guidance for the applicability of specific tests is given within this standard.
The purpose of this standard is to provide laboratory test methods for evaluating the electroacoustic performance of communication devices.
