The objective of this study was to clarify the characteristics of "visual and auditory presence."1. In FY 1999, "auditory presence" was investigated in three psychological experiments for 23 environmental sounds as stimuli.(I)The effects of kinds of sound sources on the auditory presence were examined by the method of scaling. When the sound source was moving or the sound image was large, their presences were evaluated as being high.(2)The effects of kinds of reproduction systems on the auditory presence were examined by the method of scaling. When the information on the sound image localization was preserved by a system, the presence of a sound was evaluated as being high.(3)Results of an experiment by the method of Semantic Differential with 33 pairs of adjectives were analyzed by the factor analysis and multiple regression analysis. It was indicated that the auditory presence was a multidimensional attribute that involves psychological factors of "volume", "aesthetic state", "softness", "information on the sound source", and "information on sound localization".2. In FY 2000, the effects of visual information on the auditory presence were studied. Visual information was presented to subjects with a 50-inches visual display.(1)When the visual information conveyed the situation of the original sound field correctly, the auditory presence became high. The effect was significant when the sound source was moving.(2)When the reproduced sound pressure level of a sound was about 5 dB higher than the original one, the presence was evaluated being the highest. This was considered due to the complex effect of the factors of "volume" and "information on the sound source".

本研究的目的是阐明“视觉和听觉在场”的特征。“1.在1999财政年度，“听觉在场”进行了调查，在三个心理实验的23个环境声音作为刺激。（1）采用标度法考察了不同声源对听觉在场的影响。当声源移动或声像较大时，它们的存在性被评估为高。（2）采用标度法考察了不同再现系统对听觉在场的影响。当关于声像定位的信息被系统保存时，声音的存在被评估为高。（3）采用语义差异法对33对形容词进行实验，对实验结果进行因子分析和多元回归分析。研究表明，听觉临场感是一个多维属性，涉及“音量”、“审美状态”、“柔和度”、“声源信息”和“声音定位信息”等心理因素.在2000财年，视觉信息对听觉在场的影响进行了研究。视觉信息被呈现给具有50英寸视觉显示器的受试者。（1）当视觉信息正确地传达原始声场的情况时，听觉存在性变高。当声源移动时，这种影响是显著的。（2）当声音的再现声压级比原始声压级高约5dB时，存在性被评估为最高。这被认为是由于“音量”和“声源信息”因素的复杂影响。
