To investigate the effects of low frequency vibroacoustic sound waves (16-160 Hz) on microcirculation and temperature of stomach meridian.Methods:The low frequency sound waves were played on the Five Shu Points of the stomach meridian on 30 healthy people. Then the changes of microcirculation and temperature were recorded by laser Doppler flowmetry and the effects on the points were analyzed.Results:There were different effects on the microcirculation and temperature of the stomach meridian with low different frequency acoustic waves. A1# and A0#、A2# had peak value. And the most significant effect（P<0.05） was observed on the stomach meridian with the A1# tone (58.27 Hz) and there was significant statistical difference（P<0.01） compared with other points. A1#’s effect on the microcirculation of Neiting, Xiangu, Jiexi was significantly bigger then other points（P<0.01） and its effect on the temperature of Five Shu point had no statistical difference.Conclusion:The points of stomach meridian will selectively absorb low frequency sound waves.
