Why do we hear sounds?

When someone talks, you will hear some sound waves flowing around you as they vibrate through the air in the surroundings its making you aware of what is happening around you.

The sound waves are all collected by the outer ear and travels through the ear canal and pass through the eardrum and then it sends messages to the brain telling you what kind of sound it is.

The brain understands the messages sent through the nerves in the inner ear and it helps us to understand and do what our brain is asking to do.

When you use a used  ear-bud the germs of that person will go into your ears and the germs will go through your ear-canal and it might damage your ear.And you should get a check-up by the doctor and get a proper medicine to feel well.

We need our ears to hear some sound waves or vibrations.
