Contemporary digital video, film or multimedia presentations are often accompanied by the surround sound. Techniques and standards involved in digital video processing are much more developed than concepts underlying creating recording and mixing of the multichannel sound. The main challenge in the sound processing in the multichannel system is to create an appropriate basis for the relating multimodal context of visual and sound domains. Therefore, one of the purposes of experiments is to study in which way and how the surround sound interferes or is associated with the visual context. This kind of study was hitherto carried out when two-channel sound technique was associated with a stereo TV. However, there is not much study done yet that associates surround sound and digital video presented at the TV screen. The main issue in such experiments is the analysis of the influence of visual cues on perception of the surround sound. This problem will be solved with the application of fuzzy logic to the processing of subjective test results.
