Sound phenomenon caused by reflection, where there is a slight persistence of sound after the original source has stopped speaking. Applied to remote interpretation, sometimes interpreters hear the sound of the caller with reverberation, which is an obstacle for the proper understanding of speech that should be interpreted. It is one of the most common technical incidents when the system is not configured correctly or the caller is present in a very big place without any elements to absorb sound.
