A psychophysical method combining two-intervalforced- choice (2IFC) protocol with up-down-transformed rule (UDTR) is used to study a noise-controlled technique based on stochastic resonance phenomenon. The technique is investigated by the experiments that employed a semi-automation setup producing quantitative vibration outputs added external electrical noise different from vibration stimulus. The results indicate that a certain quantity of electrical noise can induce non-monotone change of the threshold of vibration touch of subjects, which suggest occurrence of stochastic resonance. Combination of 2IFC protocol and UDTR can greatly remove subjects? psychological influences and guarantee the experimental method to be objective.
