Evaluation of Spatial Impression Comparing 2ch Stereo, 5ch Surround, and 7ch Surround with Height Channels for 3D Imagery

Three-dimensional (3D) imagery is now widely spreading as one of the next visual formats for Blu-ray or other future media. Since more audio channels are available with future media, the authors aim to find the suitable sound format for 3D imagery. A pairwise comparison test was carried out comparing combinations of 3D and 2D imagery with 2 channel stereo, 5 channel surround and 7 channel surround sound (5 channel surround plus 2 height channels) asking better depth sense and better match between visual and audio images. The results show that 3D imagery with 7 channel surround gives the highest sense of depth and match of visual and audio images.
