Comparison rating tests use two-sided scales for signal processing effects
Evidence
In situations where the processed signal could be evaluated as being either better or worse, a comparison category-rating (CCR) test can be used. Its rating scale is shown in Table 7.3 and it can be seen that it is a symmet ric two-sided scale. Listeners are asked to rate the two signals presented in terms of the quality of the second signal relative to the first. — David Howard, Jamie Angus, coustics and Psychoacoustics, 2378
