心理声学实验考察了听觉存在的基本特征，这是充分理解存在的多模式感觉的第一步。23个声音被用假人头双耳记录下来，并通过耳机复制给四个受试者。实验采用经URA修正的Scheffe配对比较法，使用五个类别的量表。方差分析表明，以听觉呈现为主的效应达到极显著水平。作为缩放的结果，运动声源的声音被评估为具有比固定声源的声音更高的存在。至于后者，声音图像较大的声音被评为具有相对较高的存在感。然而，除主效应外，其他效应以及它们之间的交互作用也是显著的。在交互作用中，主效应的个体差异往往被解释为受试者对涉及听觉存在的心理因素的权重的差异。
A psychoacoustical experiment was conducted to examine the basic characteristics of auditory presence as the first step to obtain a full understanding of the multi-modal sensation of presence. Twenty-three sounds were binaurally recorded using a dummy head and reproduced to four subjects by headphones. The experiment was carried out using Scheffe's paired comparison method modified by Ura using a scale of five categories. Analysis of variance revealed that the auditory presence as the main effect was highly significant. As a result of scaling, the sounds of moving sound sources were evaluated as having a higher presence than the sounds of stationary sound sources. As for the latter, sounds with larger sound images were rated as having a relatively higher presence. The effects other than the main effect and the interactions between them, however, were also significant. In the interactions, the individual differences for the main effect tended to be explained as the difference in weights of the subjects on the psychological factors involved in the auditory presence.
