Measured in decibels, noise intensity can range from zero, the quietest sound the human ear can detect, to over 160 decibels.
按分贝计算，噪音强度可以从零（人耳所能感到的最低声音）到160分贝以上。

Finally, the variation of the normalized covariance function of intensity with different strengths of turbulence under zero inner model is discussed in detail.
最后讨论了零内尺度模型下归一化强度协方差函数随湍流强度的变化情况。

On the basis of structure design of optical system and parameter option of optical components, the visibility of interference fringe with zero background intensity is optimized.
