Hearing loss can occur due to various factors. The most common type of hearing loss is called sensorineural hearing loss, which is caused by damage to the hair cells in the inner ear or problems with the auditory nerve. This type of hearing loss is often age-related or a result of prolonged exposure to loud noise. Another type is conductive hearing loss, which is caused by problems in the outer or middle ear, such as earwax buildup, fluid accumulation, or structural abnormalities. There can also be a mixed hearing loss, which is a combination of both sensorineural and conductive hearing loss. In some cases, hearing loss can be temporary or reversible, while in others, it may be permanent. It is important to consult with a hearing healthcare professional to determine the cause and appropriate treatment for hearing loss.
