Spatially Dynamic Sound Quality Evaluation: A Literature Study

In the context of quality evaluation of reproduced sound, it is unknown if existing sensory evaluation methods for stationary spatial sound conditions would also work when sound sources or listeners move during the formation of a quality judgement in the listener’s mind. To investigate this problem, we review literature in the fields of sound quality evaluation and dynamic sensory evaluation. We also describe specific methodologies for the temporal assessment of food quality and present them as potential candidates for spatially dynamic sound quality evaluation. Finally, we discuss the results of a pilot experiment where we implemented the Temporal-Check-All-That-Apply (TCATA) methodology to evaluate the sound quality of spatially dynamic sound stimuli.
