“…This paradigm is linked to advances in spatial audio reproduction [8,11,14] as, unlike traditional channel-based methods, the reconstruction of a virtual sound scene can be optimised to a given reproduction setup or listening environment [23]. Along with the advantages it brings to spatial audio reproduction, objectbased audio offers possibilities for greater personalisation, interaction and adaptation of content [1] [18].…”

Mobile devices enable users to consume media with audio content in a wide range of contexts, with environmental noise being present in many of these. Several methods exist that aim to improve the experience of mobile listening by utilising information about the environmental noise, such as volume and dynamic range adaptation. This paper explores a fundamentally different approach to improving the mobile listening experience by using the object-based audio paradigm, where individual audio sources are mixed in response to each specific listening context. Three experimental studies, containing both quantitative and qualitative aspects, are presented which investigate whether environmental noise influences preference of background-foreground audio object balance in a mix. The results indicate that environmental noise can influence the preferred audio mix and that the nature of the adaptations made is dependent upon both audio content and user. Additionally, qualitative analysis provides an understanding of the role of environmental noise on preferred audio mix. It is believed that the content adaptation method explored in this paper is a simple yet useful tool for adapting content to suit both the context and the user.

“…Finally, in object-based audio, the sound field is represented as a set of audio objects-an object constitutes an audio stream for an individual component of a scene (such as an actor's voice) or a collection of components (such as a choir) with metadata that provide enough information for the renderer to determine how to reproduce the object. The metadata required are determined by the rendering method; however, simple properties such as the object position and level are common to the majority of metadata schemas [8,9]. The rendering process could theoretically be performed using a number of different algorithms, but often uses VBAP.…”

“…While the VBAP [35] is widely considered as a standard technique for 3D sound panning, new techniques for 3D sound recording [39][40][41] and upmixing [42][43][44] are being developed. Furthermore, the recently standardized MPEG-H 3D audio codec [45] offers a highly efficient, object-based coding and transmission of 3D audio for domestic broadcasting.…”

Early studies found that, when identical signals were presented from two loudspeakers equidistant from the listener, the resulting phantom image was elevated in the median plane and the degree of the elevation increased with the loudspeaker base angle. However, sound sources used in such studies were either unknown or limited to noise signals. In order to investigate the dependencies of the elevation effect on sound source and loudspeaker base angle in details, the present study conducted listening tests using 11 natural sources and 4 noise sources with different spectral and temporal characteristics for 7 loudspeaker base angles between 0• and 360• . The elevation effect was found to be significantly dependent on the sound source and base angle. Results generally suggest that the effect is stronger for sources with transient nature and a flat frequency spectrum than for continuous and low-frequencydominant sources. Theoretical reasons for the effect are also discussed based on head-related transfer function measurements. It is proposed that the perceived degree of elevation would be determined by a relative cue related to the spectral energy distribution at high frequencies, but by an absolute cue associated with the acoustic crosstalk and torso reflections at low frequencies.
