International Conference on Immersive and 3D Audio
Abstract
The aim of this study is to investigate the relationship between the perceived width and different interpolation
setups of a line source, and whether it is possible to reduce
interpolations of a line source in a virtual open urban space.
In order to auralise sound sources efficiently and accurately,
the subjective evaluation was carried out in accordance with
Virtual Reality (VR) with spatial audio. The results show that
when the audible angle between adjacent interpolation points of
a line source is lowered to 1◦
, the perceived width of the line
source will significantly improve under VR experience. When the
angle is less than 1◦
, the variation in points interpolation does
not significantly affect the perceived width. This improvement
may enhance the immersion during subjective evaluation, thus
creating a more realistic experience
