在本研究中，我们通过调查和实验来考察距离对声音的反射是否会导致现实感的提高，以及是否可以通过再现每个观众都可以轻松构建的环境中的距离感来增强存在感。其基本思路来自于新冠疫情导致的网络赛事增多，以及观看网络赛事时失去距离感和现实感的时代需求。从研究第一阶段对“现实感”的调查结果可以看出，“现实感”是由多种感官元素组成的。因此，我们认为，如果声音反映了距离感，它会导致“立体感”和“因果感”的增强，这是“存在感”的组成部分，从而导致观看视频时“身临其境”的感官现实感增强。此外，由于各种原因，声音会被衰减，在大型活动场所，“声音因与声源的距离而衰减”会到达大多数座位。为了再现距离感，研究人员进行了两种实验，以确认人们是否认识到距离感，并检查这种距离感是否可再现。从结果来看，音频信息几乎可以准确地感知到与物体的距离，并且“距离感知”可以在一定程度上被音量变化所改变。识别距离可以提高立体感，立体感是真实感的组成部分之一，人们认为将声音感知到的距离感与图像感知到的距离感相匹配可以提高“因果感”。因此，根据实验结果，我们认为可以通过根据视频内容改变声音的音量来增强存在感。即使是在一个通常可以调整的回顾环境中，比如在参加在线活动时。
In this research, through the survey and experiments, we examined whether the reflection of distance to sounds leads to an improvement in the sense of reality, and whether it is possible to enhance the sense of presence by reproducing the feeling of distance in environment that each of audience can easily build. The basic idea is from the needs of the times: the increase in online events due to the spread of COVID-19, and the loss of sense of distance and lack of realism when watching online events. From the survey results on ‘sense of reality’ at the first stage of the research, it became clear that ‘sense of reality’ is composed of multi kinds of sensory elements. Therefore, it is thought that, if sounds reflect sense of distance, it would lead to the enhancement of the ‘three-dimensional feeling’ and the ‘sense of cause and effect’, which are components of the ‘sense of presence’, and thus this results in the enhancement of the sensory reality of “being there” when viewing a video. Also, the sound is attenuated by different kinds of causes, and in the large-scale venues where events take place, it is the case that the ‘sound attenuated by the distance from the sound source’ reaches most of the seats. To reproduce a sense of distance, two kinds of experiments were conducted to confirm whether people recognize it and to check whether it is reproducible. From the results, it has been shown that the feeling of distance from the object can be perceived almost accurately by the audio information and the ‘distance perception’ can be altered to some extent by the volume change. Recognizing distance leads to an improvement in the three-dimensional sense, which is one of components of the sense of reality, and it is thought that matching the feeling of distance perceived by sound and the feeling of distance perceived by the image can improve the ‘sense of cause and effect’. Therefore, based on the results of the experiment, it is considered possible to enhance the sense of presence by changing the sound volume in line with what is on the video. Even in a re-viewing environment that can be generally adjusted like when participating in an event online.
