Abstract
Perceptual measures are usually considered more reliable than instrumental measures for evaluating the perceived level of reverberation. However, such measures are costly in both time and money, and, due to variations in stimuli or assessors, the resulting data is not always statistically significant. Therefore, an efficient perceptual measure of the perceived level of reverberation is needed. We compare the use of a multiple stimuli test with the use of pairwise comparison for the evaluation of the perceived level of reverberation. The results suggest that using multiple stimuli is preferable to pairwise comparison as long as the number of conditions to be compared is not too large. Additionally, we use the results from the conducted perceptual measurements to examine the reliability of existing instrumental measures of the perceived level of reverberation. Our observations show which instrumental measures are effective in highlighting differences between RIR characteristics and which ones have to be preferred if one aims at predicting the level of reverberation perceived by a human assessor.
