Abstract

A study was conducted to examine whether the perception of vibration at one hand can be masked by vibration presented to the contralateral hand. Thresholds for the perception of vibration at the right hand were determined while applying masking vibration to the left hand. Ten males aged between 21 and 28 years participated in the experiment and all subjects were right handed, healthy, and had not been exposed to severe hand-transmitted vibration. The subjects participated in two sessions on different days and each session consisted of threshold for the masker and threshold of the test stimulus with the masker. With the 125-Hz masker applied to the left hand, no significant differences in thresholds for the perception of 125-Hz vibration applied to the right hand is observed. There were no significant differences in 125-Hz thresholds between the 16-Hz and 125-Hz maskers at any of the six masker levels.
