Types of hearing loss (Sensorineural)
Inner ear hearing loss
This type of hearing loss happens when the delicate nerve fibers in the inner ear get damaged. This stops them transmitting sound properly. It can be caused by excessive exposure to noise, but the most common causes of sensorineural hearing loss are the natural processes of aging. For some the sensory cells wear out already at the age of 50 whereas others have only negligible hearing loss even at the age of 80. This condition is permanent in most cases.
