How Does Sound Travel From The Object To Your Ear?

When some thing makes a noise it is actually vibrating, these vibrations affect the air like when you throw a stone in a pond.
These waves of air go into your ear and hit your eardrum. Your eardrum then vibrates and you have  three small bones attached to your ear drum and then a nerve that detects the vibration.
Your brain turns the input from this nerve into sound.

To be able to hear what is there, the sound makes vibrations in the air, these vibrations hit the ear drum in your ear, then three tiny bones in your ear start to move from the vibrations hitting the eardrum. The tiny bones send more vibrations through another part of your ear and are detected by nerves. The nerves send the message to the brain and develops it so that you can understand it.

The thingy travels when you shove I tin your ear and then push it up to your brain and then squish it in your brain and then you hear ME!
