Using Auditory Noise to Enhance the Fine-Motor of Human´s Hand Due to Cross-Modal Stochastic Resonance

This paper studied cross-modal stochastic resonance between auditory pathway and somatosensory pathway. We used peg-board to test the fine-motor performance of the hand under different auditory noise. The performance was a U-shape function of the intensity of different levels of auditory noise which was a typical characteristic of stochastic resonance. Optimal auditory noise can largely improve the fine-motor performance. Our result suggested that auditory noise can be used in improvement of hand accuracy in ordinary life and some special work.
