The Ear & Hearing

Front

What is the main function of the ear?

Back

The main function of the ear is to detect sound waves and convert them into nerve impulses that the brain can interpret.

Front

What part of the ear collects sound waves?

Back

The Pinna (or outer ear) collects sound waves and directs them into the ear canal.

Front

What is the role of the ear canal?

Back

The ear canal channels sound waves from the outer ear to the eardrum.

Front

What are vibrations in the context of sound?

Back

Vibrations are rapid back-and-forth movements that create sound waves.

Front

What is the eardrum?

Back

The eardrum is a thin membrane that vibrates when sound waves hit it, helping to transmit sound to the inner ear.

Front

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

Back

The three tiny bones are called the Hammer (Malleus), Anvil (Incus), and Stirrup (Stapes).

Front

What is the cochlea?

Back

The cochlea is a spiral-shaped structure in the inner ear that converts sound vibrations into nerve impulses.

Front

Where does sound processing occur in the brain?

Back

Sound processing occurs in the auditory cortex, located in the temporal lobe of the brain.

Front

What is the difference between sound waves and light waves?

Back

Sound waves require a medium (like air or water) to travel, while light waves can travel through a vacuum.

Front

What is an example of a place where sound cannot travel?

Back

Sound cannot travel in space because it is a vacuum and lacks a medium.
