Practice Listening: Multiple Choice, Single Answer ID: #40079 Short The ear
Instructions ›
You will see a video explaining the process of how the ear detects and processes sound. Listen to the recording and answer the multiple-choice question by selecting the correct response. Only one response is correct.

Transcript:

The ear is designed to collect sound waves traveling through the air. The external ear canal funnels the sound waves to the tympanic membrane, commonly known as the eardrum. Sound waves bombard the eardrum and create a vibrating motion. This motion is transmitted through the three ossicles, the malleus, the incus, and the stapes. Then on to the cochlea, the spiral-shaped, fluid-filled organ. Movement of the fluid stimulates the nerves to send impulses to the brain, which we recognise as sound.

What role do the ossicles play in the process of hearing?

Option 2: "They transmit vibrations to the cochlea."

Explanation: This option is correct as the text states that the vibrating motion created by the eardrum is transmitted through the three ossicles to the cochlea. This is a direct description of their role in the hearing process.

Option 1: "They collect sound waves from the air."

Explanation: This option is incorrect because the text specifies that the ear is designed to collect sound waves, but it is the external ear canal that performs this function, not the ossicles. The ossicles are involved later in the process.

Option 3: "They stimulate the nerves to send impulses to the brain."

Explanation: This option is incorrect because the text indicates that it is the movement of fluid in the cochlea that stimulates the nerves to send impulses to the brain, not the ossicles.

Option 4: "They funnel sound waves to the tympanic membrane."

Explanation: This option is incorrect as the text clarifies that the external ear canal funnels sound waves to the tympanic membrane, while the ossicles do not perform this function.
