Title	Speech and multimedia Transmission Quality (STQ); Subjective test methodologies for the evaluation of echo control systems Subjective test echo
Scope and Field of Application	The present document provides test methodologies for the subjective assessment of disturbances caused by echo control systems in speech communication devices. The listening test design takes the self-hearing of the far-end talker into account, which influences the assessment of perceived degradation. Adapted test procedures for single- and double-talk scenarios as well as a reference system with controlled degradation are taken into account. In addition, guidelines for the recording and preparation of listening test stimuli are provided.
