Recently, hybrid format audio technologies have been proposed as audio systems of new media such as broadcasting, virtual reality and cinema. However, when playing hybrid-format audio with multi-channel loudspeakers, rendering the object sound source by panning is no different from pre-rendered channel-based audio. Therefore, it is necessary to find a way to immersive reproduce the object sound source. We propose a method to maximize the immersiveness by hybrid playback of loudspeakers and headphone. It is verified through comparative evaluation that this method can obtain a meaningful performance improvement over the loudspeaker only method and also proved that it is possible to provide more immersive sound through application of hybrid playback in VR Attraction system.
