And today, we're going to have a look at a really cool piece of work that simulates the sound of virtual elastic rods made of aluminum, steel, oak tree, and rubber.

今天，我们要来看一下这个酷炫的作品，它模拟了虚拟的铝制、铁制、橡木制和橡胶弹性杆的声音。

Narrator: The team developed what they called an elastic rod model, which determined the degree to which the hair would retain its twists and springiness under different forces, like wind or water.

旁白：该团队开发了他们所谓的弹性杆模型，该模型确定头发在不同的力（如风或水）下保持其扭曲和弹性的程度。

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。
