Why does hearing decline?

Hearing loss can be caused by many factors, the following are some common reasons:

Age factor: with the increase of age, the structure of ears and auditory nerves may naturally age, leading to hearing loss. This condition is often called presbycusis.

Noise exposure: Long-term exposure to high-intensity noise environment, such as noise at work, noise from concerts or mechanical equipment, may lead to hearing loss.

Genetic factors: Some hearing problems can be transmitted through heredity, which makes some family members more prone to hearing loss.

Ear infection: Ear infection or inflammation may cause damage to the middle and inner ears, thus affecting hearing.

Ear injury: head injury, severe ear impact or other physical injuries may lead to hearing loss.

Side effects of drugs: Some drugs, especially some powerful antibiotics, chemotherapy drugs, diuretics and over-the-counter drugs, may cause hearing problems.

Cochlear problems: structural or functional abnormalities of the inner ear, such as cochlear inflammation and cochlear degenerative diseases, may lead to hearing loss.

Earplugs or earwax: Excessive earwax or foreign matter blocking the ear canal may affect sound transmission and lead to hearing loss.

Meniere's disease: This is a disease of the inner ear, which may lead to hearing loss, tinnitus and dizziness.

Chronic diseases: Some chronic diseases, such as diabetes and hypertension, may affect hearing.

Autoimmune diseases: Some autoimmune diseases, such as rheumatoid arthritis, may affect the auditory system.

Otitis media: Recurrent otitis media may lead to hearing loss, especially in children.

If you or someone around you has hearing loss, it is recommended to consult a medical professional as soon as possible to get professional diagnosis and treatment advice.
