| 摘 要： | 该文通过实验研究了不同频率、不同噪声级和不同暴露条件下的噪声对人体的心率变异的影响.实验结果表明:噪声频率和暴露条件对心率R-R间期的影响显著，噪声暴露使R-R间期减小，这种减小的趋势在噪声撤去之后还将继续一段时间. 通过对R-R间期的心率变异分析得知，在500 Hz附近的噪声使交感神经的兴奋程度小于其他频率的噪声影响.

| Abstract: | The authors studied the human's heart rate variability(HRV) which was influenced by the noise under different frequencies,different noise levels and varied noise exposed conditions.The experimental results indicated that the effects of the noise frequencies and exposed conditions on HRV during R-R interval period were significant.The noise exposing made the R-R interval period decreased and this kind of decreasing trend will last for a period of time after the noise was stopped.It is concluded that the noise near 500 Hz has less sthenic effect on the sympathetic nerve than those of the other noise frequencies. |

| Keywords: | noise heart rate variaility(HRV) R-R interval period assessment |
