Brief summary
Study the effects of 60dB and 80dB white noise, 50-70dB and 70-90dB non harmonic tones on the basic pain threshold of subjects, including the threshold and tolerance of electrical stimulation pain,the threshold and tolerance of cold pain stimulation, and the threshold and tolerance of tenderness stimulation.
Interventions
BEHAVIORALnoise stimulation
Apply non harmonic and white noise sound stimuli to the subjects, and then measure the threshold and tolerance values of pressure pain, cold pain, and electrical pain.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| mechanical pain sensitivity | from the study beginning to 30 min after the procedure | Each participant was measured using the pressure pain threshold and tolerance (tested by a pressure meter), which lower value present higher pain sensitivity |
| cold pain sensitivity | from the study beginning to 30 min after the procedure | Each participant was measured using the cold pain threshold and tolerance (tested by immersion the hand in 4℃ water), which lower value present higher pain sensitivity |
| electrical pain sensitivity | from the study beginning to 30 min after the procedure | Each participant was measured using the cold pain threshold and tolerance (tested by a electrical stimulator), which lower value present higher pain sensitivity |
