Sounds sounds sounds!!!!!!!!!!



We hear sounds because  sound waves vibrate in the air. The brain makes sense of the nerve’s messages and helps us to recognise the sounds.


The anvil hammer and stirrup wobble and moves the liquid into the ear when we hear a sound.Our sound wave causes the air-drum to vibrate in our ears.


The nerves picks up  the liquid’s movement and send messages to the brain. The sound waves are collected by the outer ear.

We hear sounds because if we didn’t have ears then we wouldn’t hear sounds a  it is important that we look after our eardrums so that we can appreciate all the wonderful sounds around  us .This is a left human ear.
