Your Ears (1964)

[Music] [Applause] [Music] listen can you hear all those seagulls how many can you [Music] hear and listen to this C do you hear the echo how about this how many different things do you hear with your ears new sounds Whispers let's go and play [Music] signals you use your ears all day long well where have you two been all morning you use your ears whether you're listening to stories or just talking about a picnic you use your ears when you're answering questions could you please tell us where the main road is and giving directions you hear things all the time but how often do you notice sometimes you can't hear then you notice I say thank you very much please come and see us sometime [Applause] uhhuh sometimes you hear sounds that are warning [Applause] [Applause] your ears are useful in many ways there's more of your ear than you can see most of your ear is where you can't see it inside your head your ear is like a funnel collecting sound waves and directing them to the inner ear the sound waves strike a tight sheet called the eardrum making it move the eardrum is attached to three tiny bones that move whenever the eardrum moves these parts of the ear are so sensitive that even a whisper sets them vibrating the vibrations are felt by many nerve cells also in the inner ear and these nerve cells send signals to your brain about the sounds around you but sometimes things can go wrong a bad knock could break the eardrum then could you hear and if you blow your nose too hard you may Force germs up through a tube that leads to the middle ear when germs get in the middle ear they may cause infections which interfere with your hearing when you know how delicate your ears are you want to take good care of them because you use your ears all day long you use your ears to hear many different things go roll roll your Bo gently down the street [Music] n [Music] [Applause] [Music]
