Perceptual Comparison of 3D Audio Reproduction With and Without Bottom Channels

“…Numerous previous studies have examined the perceptual effects of height channels on audio reproduction, many of which are effectively summarized by Roginska and Geluso [4] and Paterson and Lee [15]. At this time, however, only two studies are known to have specifically examined the perceptual effects of bottom channels in 3D audio reproduction.…”

Spatial sound and emotions: A literature survey on the relationship between spatially rendered audio and listeners’ affective responses

“…Technologically, this is accomplished using either an array of loudspeakers or a pair of headphones employing binaural technology. For a comprehensive overview of the technologies employed to reproduce spatial audio, see [41]- [43]. The following terms are used in this paper to describe listeners' emotional reactions to spatial sound:…”

“…The other four used more complex arrangements with multiple loudspeaker layers at different elevations [20], [28], [29], [30]. Only three out of twelve loudspeaker-based studies provided reports of applying well-established spatial audio rendering methods, such as Ambisonics [43] -used by Tajadura-Jiménez et al [34], Wave Field Synthesis [56] -utilized by Ooishi et al [29], and Sound Field Synthesis [57] (based on Higher Order Ambisonics) -employed by Hyodo et al [21]. The techniques employed to record and reproduce spatial audio in the remaining loudspeaker-based studies are unknown or scarcely reported.…”
