IEEE Standard Methods for Measuring Transmission Performance of Analog and Digital Telephone Sets, Handsets, and Headsets

Practical methods for making laboratory measurements of electroacoustic characteristics of analog and digital telephones, handsets and headsets. The methods may also be applicable to a wide variety of other communications equipment, including cordless, wireless and mobile communications devices. Measurement results may be used to evaluate these devices on a standardized basis. Application is in the frequency range from 100 Hz to 8500 Hz. This edition incorporates IEEE Std 269a™-2007. Other substantive changes have been made since the 2002 edition.
