室内音場の主観的印象に対する視覚情報の影響及び視聴覚間の違和感との関連性

摘要

The purpose of this study is to clarify the influence of visual information from room interior on auditory impression for indoor sound field, and to acquire knowledge which contributes to architectural acoustic design. In this report, auditory impressions and incongruity were measured when auditory stimuli (room impulse responses) and visual stimuli (virtual reality images of room interior) were presented to subjects individually (in single-modal presentation) or simultaneously (in multi-modal presentation). As a result, changes of auditory impression were observed when presentation mode was altered, but relationship of the changes with incongruity between auditory and visual stimuli could not be detected.%仕様の異なる3つの室內空間の内観と音場を表す視聴覚刺激を用 いて、聴覚刺激の単独提示及び視覚刺激と聴覚刺激の同時提示にお ける聴覚印象及び違和感を測定する主観評価実験を行った。聴覚刺 激とその提示方法が異なる2種類の実験を通して、提示モードによ る聴覚印象の変化を明らかにすると共に、その変化に対する違和感 による影響を考察した。その結果と得られた知見を以下にまとめる。
