17. Amongst which of the following component captures sound in the environment?
- Tympanic membrane
- Ossicles
- Pinna
- None of the mentioned above
Answer: C) Pinna
Explanation:
Pinna is the external ear that aids us to capture sound in the environment. The pinna's distinct form and structure enable it to gather sound waves from its surroundings. As sound waves move through the air, they collide with the pinna's curves and ridges. This contact alters the incoming sound waves, allowing the pinna to selectively amplify or attenuate certain frequencies.
