Abstract
The three-dimensional audio technology called Ambisonics has garnered considerable attention as a high-definition sound space reproduction technique for a sense of presence in virtual reality (VR). In this study, we examined how different sound reproduction methods and source positions affect sound space perception in a headphone-based listening environment. Therefore, environmental sound sources recorded using the Ambisonics method were changed to various reproduction methods using signal processing. The sound sources were converted into four types of reproduction methods: monaural, two stereo reproductions (figure-of-eight and cardioid), and binaural reproduction with Samurai head-related transfer functions (HRTFs). The results showed that the cardioid and binaural playback methods were rated higher in terms of stereoscopic effect and sense of presence compared to the other playback methods. Additionally, it was observed that the cardioid and binaural playback method could achieve greater accuracy in sound localization.
