Sense Organ II: The sense of hearing (ears) - ClassNotes.ng
Skip to content
We hear with our ears. The ear is the sense organ with which we hear sounds made by thins around us. Some people have hearing aids to help them hear sounds. People who cannot hear at all are deaf.
There are sounds all around us. The sounds that we hear are vibrations that come into our ears. The vibrations send signals to our brains and our brain tells us what we hear. For example, when we hear the sound of a bell, even without seeing the bell, we know it is bell.
Sounds made by Man
The baby cryingThe boy whistlingThe girl dancingThe boy laughing.
Sound made by animals
A cock crowsA lion roarsA dog barksA cat meows
Sound made by non- living objects
A car hootsA telephone rings
