Abstract
In this paper, a method combining the distance variation function (DVF) and image source method (ISM) is presented to generate binaural 3D audio with accurate feeling of distance. The DVF is introduced to indicate the change in intensity and inter-aural difference when the distance between listener and source changes. Then an artificial reverberation simulated by ISM is added. The reverberation introduces the energy ratio of direct-to-reverberant, which provides an absolute cue to distance perception. The distance perception test results indicate improvement for distance perception when sound sources located within 50 cm. In addition, the variance of perceptual distance was much smaller than that using DVF only. The reduction of variance is a proof that the method proposed in this paper can generate 3D audio with more accurate and steadier feeling of distance.
