That's about 10 decibels lower than a jet engine.

这是10分贝比喷气发动机低。

This is a logarithmic scale which means that increasing the number of decibels corresponds to a multiplication of intensity.

分贝单位是对数比例，是音量的度以倍数选进。

Noise is measured in decibels on a logarithmic scale (such that a doubling of sound energy equates to a 3 decibel increase).

噪音分贝来衡量，就对数规模（例如，一个翻一番无害的能源相当於3分贝增加）。

Has the scientist to do the experiment: When noise intensity when 90 decibels, in retina's rod cell difference radiance's sensitivity starts to drop, distinguishes the time which the weak light responded also to lengthen; When noise when 95 decibels, some 2/5 person mydriasis; When the noise amounts to 115 decibels, the eye reduces 20% to the radiance compatibility.

有科学家做过实验：当噪音强度在90分贝时，视网膜中的视杆细胞区别光亮度的敏感性开始下降，识别弱光反应的时间也延长；当噪音在95分贝时，有五分之二的人瞳孔放大；当噪音达到115分贝时，眼睛对光亮度的适应性降低20%。

And these emit…150 decibels over a distance of about a nautical mile….

150分贝以上的距离大约海里。。。
