The Science of Hearing Quiz

What is the main function of the pinna in the outer ear?

• To maintain balance

• To collect sound waves and direct them to the ear drum

• To convert sound waves into electrical signals

• To amplify sound waves

What is the purpose of the ear drum?

• To separate the outer ear from the middle ear

• To amplify the pressure of sound waves

• To convert vibrations into electrical signals

• To collect sound waves and direct them to the ear drum

What are the three bones in the middle ear collectively called?

• Auricle, Tympanic Membrane, and Eustachian Tube

• Pinna, Ear Drum, and Cochlea

• Malleus, Incus, and Stapes

• Hammer, Anvil, and Stirrup

What is the main function of the ossicles in the middle ear?

• To maintain balance

• To amplify the pressure of sound waves

• To convert vibrations into electrical signals

• To separate the outer ear from the middle ear

What is the purpose of increasing the pressure of sound waves in the middle ear?

• To set the liquid in the inner ear in vibration

• To convert vibrations into electrical signals

• To maintain balance

• To transfer vibrations from the ear drum to the inner ear

What is the main function of the cochlea in the inner ear?

• To maintain balance

• To convert vibrations into electrical signals

• To collect sound waves and direct them to the ear drum

What happens when the stirrup hits the cochlea?

• The pinna collects sound waves

• The liquid in the cochlea starts vibrating

• The ossicles amplify the pressure of sound waves

• The ear drum starts vibrating
