Abstract

This study investigates the effect of mechanical ground on the perceived intensity of vibration transmitted through a handheld object. To this end, we carried out an intensity matching experiment in which the points of subjective equality were measured between grounded and ungrounded conditions. Results showed that the grounded vibrations were perceived to be 1.63–1.86 times stronger than the ungrounded vibrations. This intensity difference was decreased with increasing vibration frequency. Our results are in line with the general fact that afferent movements, which are more apparent under the ungrounded condition, may induce tactile suppression.
