我们为什么能听见声音?

Why can we hear sounds?

耳朵里有一层小鼓膜,声音一来它就抖动,把消息传给大脑。
Your ear has a tiny eardrum that shakes when sound arrives and sends the message to your brain.

声音跑得有多快?

How fast does sound travel?

声音在空气中大约每秒走340米,比光慢很多,所以远处我们先看见再听见。
Sound travels about 340 meters per second in air, far slower than light, so from far away we see before we hear.

耳朵怎样把声音传给大脑?

How does the ear send sound to the brain?

声波让鼓膜和耳里的小骨头振动,再变成神经信号一路传给大脑。
Sound waves shake the eardrum and tiny ear bones, which turn the motion into nerve signals sent to the brain.
