Hearing loss can be divided into four categories depending on the level of hearing loss*: mild, moderate, severe and profound. Watch the video to understand these four levels better.*World Health Organization, 2016
The ear is made up of three parts:
- the outer ear
- the middle ear
- the inner ear
Knowing how the ear works is important for understanding hearing loss. Hearing loss can be divided into three types depending on which part of the ear is affected.
Conductive hearing lossIf your outer or middle ear doesn’t transfer sound to the inner ear, you have conductive hearing loss. This type of hearing loss may be temporary or reversible. Often it can be treated by removing a blockage from the ear.
Sensorineural hearing lossIf your hearing loss is located in the inner ear or in the nerve that carries sound to the brain, you have sensorineural hearing loss. This type of hearing loss is more likely to be permanent, but there are excellent treatment options available.
Mixed hearing lossMixed hearing loss means you have elements of both conductive and sensorineural hearing loss.
