Females are More Sensitive to Hand-arm Vibration than Males

HCDI research by Jeon, Ajovalasit and Giacomin has found that females are more sensitive than males to hand-arm vibration. Psychophysical response tests of 20 males and 20 females were performed using a steering wheel rotational vibration simulator and using a category-ratio Borg CR10 scale for the direct estimation of perceived intensity. The stimuli were sinusoidal vibrations in the range from 3 to 400 Hz with acceleration amplitudes from 0.04 to 27 m/s2 r.m.s.. The results suggest a nonlinear dependency of the subjective perceived intensity on both the vibration frequency and amplitude, and confirm that females perceive higher subjective intensities than males, particularly at higher frequencies and amplitudes.
