A) eardrum: performs vibrations & Brain: processes the signal is the correct answer for hearing process.
- Ears are responsible for two functions namely hearing and balance.
- Ear canal is the tube through which sound reaches the ear drum or tympanic membrane. The sound is further transmitted to three small bones which further reaches cochlea and is subsequently transferred to brain for processing.
- Pinna also knows as external ear is a vestigial organ.
