简要总结
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.

研究组 & 干预措施
noise on pain
Comparison of pain sensitivity before and after hearing noise among 15 subjects in each group.
干预措施: noise stimulation (Behavioral)
结局指标
主要结局
cold pain sensitivity
时间窗: 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
时间窗: 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
mechanical pain sensitivity
时间窗: 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
