| Popis: | Are there differences in how well loudspeaker setups are able to provide a believable illusion of footstep sounds originating from the user of an immersive virtual reality? To investigate this performance in spatial positioning via loudspeakers, a comparison of the three surround sound loudspeaker setups with different distance and elevation from the user was conducted. A fourth condition with a large amount of reverb added was also evaluated. The results showed that none of the loudspeaker setups provided an ideal performance. However, when asked to describe the position of the sounds, the nearest setup on the floor gave the best performance. When evaluating what degree the sound were coming from themselves, there were no significant difference found between the two highest rated, the closest setup on the floor and the distant elevated setup. On the Likert scales, the reverb condition was evaluated as the least well performing. |
