Abstract

In many listening tests for audio quality evaluation the listeners have the possibility to set loops, meaning they can focus on a smaller part of the audio signal and listen to that repeatedly. In previous papers we already showed that experienced listeners set more loops and that learning to set loops increases the ability of the listener to perceive artifacts. Now we analyze to what extent these loops chosen by the listener vary from listener to listener and whether the ratings are influenced by the choice of loops of the listener. We show that—depending on the stimulus—listeners who set different loops may also rate significantly different.
