Final answer:
Amari suffers from sensorineural hearing loss, which cannot be medically restored because it involves damage to the inner ear or nerve pathways related to hearing.
Step-by-step explanation:
Amari, who was born without the ability to hear and cannot have his hearing restored medically, suffers from sensorineural hearing loss. This type of hearing loss typically occurs due to problems within the inner ear, such as damage to the nerves in the cochlea or the loss of hair cells in the organ of Corti.
Unlike conductive hearing loss, which involves issues with the transmission of sound through the outer and middle ear, sensorineural hearing loss involves damage to the sensory cells or nerve pathways from the inner ear to the brain. Hearing aids may offer some improvement by amplifying sounds, but they cannot restore the normal functioning of the damaged hair cells or nerve tissues. In some cases, cochlear implants may provide a means to bypass damaged areas and stimulate the auditory nerve directly.
