这标志着三个月以来的第二次衰减。
通过具体的计算发现，由撞击带来的直接效应是有限的，在短时间内会迅速衰减，但由此引发的二次效应却是十分显著的。
Based on the calculation of our model, we find that the direct effects of the impact are limited and will attenuate in a short time.
这二次实测，一次为波浪成长阶段，而另一次为波浪衰减阶段。
The two measured wave data was once a wave generation stage, and another time a decay stage.
我们然后计算二次测量之间的区别并且引起多少噪声衰减一个数字因素耳机提供在整个可听见的频率范围。
We then calculate the difference between the two measurements and generate a numerical factor of how much noise attenuation the headphones are providing over the entire audible frequency range.
