Which as we’ve just said is determined by its amplitude.

—有关。刚才说过了这由它的振幅决定。

Because it's the amplitude that determines how loud a sound appears to be to humans.

因为振幅决定着声音对人类来说有。

The wave’s wavelength and frequency determines their hue, and their amplitude determines their intensity or brightness.

决定光线的色调，振幅决定了强度或亮度。

A few important aspects of this wave include the frequency and the amplitude.

该波的几个重要方面包括频率和振幅。

And as you can see, the amplitude is increasing.

正如您所看到的，振幅正在加。

So, the cosine of theta is equal to the (ball’s position) divided by its (amplitude).

因此， theta 的余弦等于（球的位置）除以它的（振幅）。

The amplitude of a sound wave determines how loud it is.

声波的振幅决定了它的度。

When the amplitude is modulated or changed, we hear this as a change in volume.

当振幅被调制或改变时，到的是音量变化。

Larger numbers mean higher sound pressure, what's called amplitude.

数字越大意味着声压越高，也就是所谓的振幅。

They have overtones of different frequencies and relative amplitudes.

它具有不同频率和相对振幅的泛音。

The heartbeat is signaled by changes in amplitude.

跳通过振幅的变化发出信号。

The heart rate was the same, but the amplitude dropped.

率没变 但振幅下降了。

In other words, if you double the wave’s amplitude, you get four times the energy.

换句话说，如果你将波的 振幅加倍，你会得到四倍的能量。

(half of the spring constant), times the (amplitude squared).

弹簧常数的一半乘以振幅的平方。

Well, if we're getting disturbed that much, we could call that the amplitude.

好吧，如果受到如此大的干扰，可以称之为振幅。

This would be the amplitude as well.

这也是振幅。

I asked Miguel to show me some waves with different frequencies but the same amplitude.

让米格尔给展示一些频率不同但振幅相同的波。

And! The radius of the circle is the same as the ball’s amplitude on the spring.

和！ 圆的半径与球在弹簧上的振幅相同。

When you have notes that are very close together, the result is amplitude modulation.

当您的音符非常靠近时，结果就是振幅调制。

Thousands of amplitudes for every single second of audio!

每一秒的音频都有数千个振幅！
