- This study was part of an ongoing research project that explores and evaluates possible ways of using auditory cues to influence the perception of depth in 3D/immersive audiovisual presentations.
Considering the role of cross-modal integration in depth perception, it was expected that manipulating auditory parameters related with depth perception would result in the viewer/listener being forced to perceive the depth of the visual objects as being altered even though the visual depth and the scene remained unchanged.
In terms of the variables studied, volume attenuation and high frequency loss of specific elements of the soundtrack were used to influence the sense of depth in stereoscopic 3D animation sequences. The two variables were studied both separately and combined. The hypotheses used for the tests were the following:
H1a: The perception of depth of a given S3D cinematic scene can be increased by attenuating the high frequency content of an accompanying broadband sound,
and
H1b: The perception of depth of a given S3D cinematic scene can be increased by attenuating the overall volume level of an accompanying broadband sound.
The study utilised a repeated-measures design and quantitative analysis, and provided statistically significant results. Results indicate that volume attenuation was effective in influencing depth perception in a number of occasions, and a related paper was published on 3D Research (Springer).
Based on these results, an additional study was designed and carried out investigating the effect of volume level alterations of the entire soundtrack, as opposed to a broadband sound. This study is presented as a separate submission under the name ‘Soundtrack Loudness as a Depth Cue in Stereoscopic 3D Media’.
