Their system would let the pressure waves that carry sound pass through if they come from the left.

如果从左边而来，他们的系统会让携带声音的压力波通过。

When you pulse the speaker, it creates a pressure wave.

当您对扬声器发出脉冲时，它会产生压力波。

This graph shows the pressure waves or waveform produced by a popping balloon.

该图显示了气球爆裂产生的压力波或波形。

See, this is essentially your body's microphone, converting sound pressure waves into electrical impulses that are eventually sent to the auditory nerve and then to the brain.

看，这本质上是你身体的麦克风， 将声压波转换成电脉冲，最终发送到听觉神经， 然后发送到大脑。

And these signals arrive at your body as different forms of energy, light and heat, sound wave pressure, even molecular vibrations in  the chemicals that we smell.

这些信号以不同形式的能量、光和热、声波压力，甚至是我们闻到的化学物质中的分子振动形式到达您的身体。

Those particles hit the next set of adjacent particles, and so on , thereby creating an expanding shell of air particles just bouncing into one another This is called a pressure wave or sound wave.

这些粒子撞击下一组相邻粒子，依此类推，从而产生一个膨胀的空气粒子壳， 只是相互反弹。 这称为压力波或声波。

And even though this might be a pressure wave that's traveling through the air, we can represent it in a way that looks a lot like our first rope that we were moving up and down.

尽管这可能是在空气中传播的压力波，但我们可以用一种看起来很像我们上下移动的第一根绳子的方式来表示它。
