Abstract

The vibrotactile perception threshold (VPT) of healthy Japanese with new equipment developed according to ISO 13091-1 was studied and the results wee compared with the ISO 1309 1-2:2003 reference data. The subjects were 30 males and 17 females aged 22 to 40 years, healthy Japanese office workers, who do not have a history of undue exposure to vibration. The VPTs of index fingers and middle fingers of right-hands were measured for 9 stimulus frequencies such as 3.15, 4, 5, 20, 25, 31.5, 100, 125, and 160 Hz. 2.5, 15, 50, 85 and 97.5 percentiles of the VPT levels of the male and the female subjects are observed. Mean and standard deviation (SD) of the VPT levels for index fingers and middle fingers of the male and the female subjects show significant differences at the 5 % significance level between the males and the females are measured only for some lower frequencies.
