The necessary tools for good hearing include the following:
- An open ear canal that is not obstructed by wax and debris.
- An intact ear drum.
- An air filled space behind the ear drum (also known as the middle ear).
- Intact and connected bones of hearing (also known as ossicles).
- A functional inner ear (also known as cochlea).
- A functional auditory nerve (also known as cochlear nerve).
- A functioning auditory system within the brain.
Any disturbance of the above factors can result in suboptimal hearing
