The decibel scale is what's used to measure the loudness of a sound and it's important to note that the scale is logarithmic.

分贝刻度是用来测量声音的响度的，而且重要的是要注意这个分贝刻度表呈对数曲线。

And this is usually represented by the nonlinear decibel scale, where a normal conversation is around 60 decibels and a rock concert is around 120 decibels.

这通常由非线性分贝标度表示，其中正常的对话约为 60 分贝，摇滚音乐会约为 120 分贝。
