Temporal Evaluation of Sound Quality using TCATA

In this paper, we present an experiment based on a method called Temporal-Check-All-That-Apply (TCATA). The experiment was carried out to study the temporal perception of various attributes of sound quality when sounds move around a stationary listener. The first goal of the experiment was to understand if we could capture any changes in the perceived quality that reflected the spatial characteristics of the sounds reproduced in the lab using loudspeakers. The second goal was to evaluate if the method could record perceptual differences between stimuli with non-expert listeners. We concluded that TCATA is a suitable method to capture changes in the perception of various sound quality attributes over time. Still, we observed that dynamic physical characteristics are not necessarily represented as dynamic perceptual characteristics in all cases. The experimental variables programme, reproduction system, trajectory of a moving sound source, and loop showed a statistically significant effect on the results. Based on our findings, we propose recommendations for future investigations.
