Sensorineural hearing loss ( SNHL) is a type of hearing loss in which the root cause lies in the inner ear, sensory organ ( cochlea and associated structures), or the vestibulocochlear nerve ( cranial nerve VIII). SNHL accounts for about 90% of reported hearing loss. [citation needed] SNHL is usually permanent and can be mild, moderate, severe ...
Hearing loss is a partial or total inability to hear. [5] Hearing loss may be present at birth or acquired at any time afterwards. [6] [7] Hearing loss may occur in one or both ears. [2] In children, hearing problems can affect the ability to acquire spoken language, and in adults it can create difficulties with social interaction and at work. [8]
Sudden sensorineural hearing loss (SSHL) is a change to the inner ear hearing status. SSNHL is a change of 30 dB HL or greater at three adjacent frequencies within 72 hours. For example, if your ...
Noise. Noise exposure is the cause of approximately half of all cases of hearing loss, causing some degree of problems in 5% of the population globally. [5] The National Institute for Occupational Safety and Health (NIOSH) recognizes that the majority of hearing loss is not due to age, but due to noise exposure.

Autoimmune inner ear disease. Autoimmune inner ear disease (AIED) was first defined by Dr. Brian McCabe in a landmark paper describing an autoimmune loss of hearing. [ 2] The disease results in progressive sensorineural hearing loss (SNHL) that acts bilaterally and asymmetrically, and sometimes affects an individual's vestibular system.
The cause is often not clear. It may be due to a virus, but it can also arise from bacterial infection, head injury, extreme stress, an allergy, or as a reaction to medication. 30% of affected people had a common cold prior to developing the disease. [1] Either bacterial or viral labyrinthitis can cause a permanent hearing loss in rare cases. [7]
