Hearing

keynotes:

Introduction to Hearing:

• Hearing is one of our five senses that helps us understand sounds around us.
• Our ears help us hear different sounds, like music, talking, and even birds chirping.

Parts of the Ear:

Outer Ear:

• The part of the ear you can see is called the pinna or auricle.
• The ear canal is a pathway that leads to the middle ear.

Middle Ear:

• The eardrum or tympanic membrane is like a drum that vibrates when sound reaches it.
• Behind the eardrum are three tiny bones: the hammer, anvil, and stirrup.

Inner Ear:

• The cochlea is a snail-shaped part that helps turn vibrations into signals for the brain.
• The auditory nerve carries these signals to the brain, so we can understand what we’re hearing.

How We Hear:

Sound Waves:

• Sound is made up of tiny waves that travel through the air.
• These waves make our eardrum vibrate.

Vibrations:

• When the eardrum vibrates, it makes the tiny bones in our middle ear move too.
• These bones help the sound travel to the inner ear.

Cochlea and Brain:

• In the cochlea, tiny hair cells pick up the vibrations and send signals to the brain.
• Our brain then understands these signals as different sounds.

Taking Care of Our Ears:

• We need to protect our ears from loud noises, like fireworks or very loud music, to keep them healthy.
• We should also clean our ears gently and not put anything too deep inside them.

Conclusion:

• Hearing is an important sense that helps us enjoy the world of sounds around us.
• Our ears have different parts that work together to help us hear and understand sounds.
