Final answer:
Deafness can be caused by various factors, including congenital deafness, age-related hearing loss, genetic predisposition, and environmental factors. Conductive hearing loss occurs due to problems in transmitting sound energy to the cochlea, while sensorineural hearing loss is the most common form and can be caused by aging, infections, medications, trauma, and loud noise exposure.
Step-by-step explanation:
Deafness can result from various causes, including congenital deafness, age-related hearing loss, genetic predisposition, and environmental factors.

Sensorineural hearing loss is the most common type and can be caused by factors such as aging, infections, medications, trauma, and exposure to loud noise.
