交通による戸建て住宅の水平方向の実測波形を用いたランダム振動に対する環境振動評価

摘要

In this study, we performed an experiment involving the measurement of the subjective perception of horizontal traffic vibration in detached houses. The objective was to investigate the influence of the predominant frequency and waveform pattern on the perception of random vibration over a wide range of frequencies.rnResults show that the predominant frequency greatly influences the perception of random vibration. Evaluation curve of perception of random vibration calculated by using predominant frequency and maximum acceleration is parallel to that of sinusoidal vibration. For 40% of the subjects, the random vibration was harder to perceive than the sinusoidal vibration. Based on the result, the authors present the conclusions derived from the evaluation of perception of random vibration.%これまで環境振動に対する知覚や心理量に着目した被験者実験でrnは，主として正弦振動を対象とした検討 他が行われ，居住性能rn評価指針 でも正弦振動の知覚に基づいて性能評価曲線が提示されrnている。一方，実環境で生じる振動は，複数の振動数成分を含み，rn振動数や振幅が時々刻々と変化するランダム振動であり，正弦振動rnに対する知覚の評価とは相違があることが指摘されてきた。
