Evaluation methods for vibrations

Abstract Interval and ratio scales in subjective response were determined for vertical and horizontal sinusoidal vibrations of the whole body in the same way as loudness level and loudness in psycho-acoustics. The sensation difference between vertical and horizontal vibrations was also observed. Next a weighted summation method in the ratio scale was examined for frequency components of compound sinusoidal and random vibrations and an evaluation method for pulsed vibrations studied. The relation between emotional response (unpleasant or intolerable) and sensation magnitude in the interval scale was examined as a possible means of assessing the vibration. Finally, a method of measurement was established for actual vibration given to a person who sat on a soft resilient cushion on a vibrator. This paper is a review of work carried out by the authors.
