초록
Children running sound as floor impact noise was evaluated in virtual reality environments, and investigated the influence of the head mounted display (HMD) and spatial sound effect using head-related transfer function (HRTF). In order to reproduce a real moving sound source, a HRTF was applied to a single impact ball sound. The annoyance level and allowable endurance limit were evaluated by changing LA,Fmax and temporal decay rate (DR) in four environmental set-ups: non-effect, only HRTF, only HMD, and HRTF and HMD. As a results, the recognition of the impact sound in the VR environment, and the sound directivity information energy significantly contributes to the annoyance response.
