Hearing Loss
Save
Hearing loss, which affects millions of people worldwide, is a condition characterized by the partial or total loss of hearing in one or both ears. It can be caused by various factors, including genetics, aging, noise exposure, and infections. Hearing loss can have a significant impact on an individual's quality of life, communication abilities, and social interactions.
Causes of Hearing Loss
Noise exposure: Prolonged exposure to excessive noise, such as industrial machinery, firearms, or loud music, can damage the delicate structures of the inner ear, leading to noise-induced hearing loss (NIHL).
Age-related hearing loss: Presbycusis, also known as age-related hearing loss, is a gradual decline in hearing ability that occurs as a natural part of the aging process. It typically affects high-frequency sounds first.
Genetic factors: Certain genetic disorders can cause hearing loss, such as otosclerosis, which affects the middle ear, and Usher syndrome, which includes hearing loss as part of a wider range of symptoms.
