What's not going to work well with that are higher frequency sounds.

无法很好处理的是高频声音。

They dissected the soundwaves of each vocalization and looked at things like how long the call lasted and each sound's frequencies.

她们剖析了每个声音的声波，并观察了叫声持续时间和声音频率。

We can know actually model the kind of sound that resonating chamber would make and turns out the deep sound, low frequency sound.

我们可以模拟出共振腔所发出的声音然后制造出低音，低频的声音。

It’s similar to how echolocating bats will use high frequency sound to zero in on their prey.

这类似于回声定位蝙蝠如何使用高频声音将其猎物归零。

We can sense differences in weight of just 2% and we can detect differences in sound frequencies of less that one half of a percent.

我们可以感觉到只有 2% 的重量差异，我们可以检测到不到 0.5% 的声音频率差异。

The sound emerging from these elastic rods is particularly difficult to simulate because of the fact that sound frequencies vary quite a bit over time, and the objects themselves are also in motion and subject to deformations during the simulation.

要模拟这些弹性杆发出的声音是非常困难的，因为声音频率随着时间的推移会有相当大的变化，而且物体本身仍然在运动中，在模拟过程中还存在变形。
