Question

What are the causes of deafness?

Hint:

Regular hearing check-ups and avoiding exposure to loud sounds can help prevent some types of hearing loss.

Answer 1

Deafness can be caused by several factors, which may be either genetic, environmental, or due to an injury or illness. Some of the main causes of deafness are:

Genetic Factors: Inherited conditions or genetic mutations can lead to hearing loss, either from birth or developing later in life.
Age-Related Hearing Loss (Presbycusis): As people age, the sensory cells in the inner ear may degrade, leading to gradual hearing loss.
Infections: Certain infections, such as meningitis or measles, can cause hearing loss. Otitis media (middle ear infection) is also a common cause of temporary hearing loss in children.
Loud Noise Exposure: Prolonged exposure to loud sounds or sudden loud noises (like explosions) can damage the hair cells in the inner ear, leading to hearing loss.
Trauma or Injury: Injury to the head or ear can result in permanent damage to the hearing structures.
Ototoxic Medications: Certain medications, such as some antibiotics or chemotherapy drugs, can damage the inner ear and cause hearing loss.
Earwax Blockage: Excessive earwax can block the ear canal and prevent sound from reaching the eardrum, leading to temporary hearing loss.

Conclusion:
Deafness can occur due to various factors, including genetic, environmental, and medical causes. Prevention and early diagnosis are important for managing hearing loss.
