Deafness can be broken down into four different types of hearing loss: conductive hearing loss, sensorineural hearing loss, mixed hearing loss, and auditory neuropathy spectrum disorder. All of these forms of hearing loss cause an impairment in a person's hearing where they are not able to hear sounds correctly.
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]

The institute also ...
Others who grew up blind and later became deaf are more likely to use a tactile mode of spoken/written language. Methods of communication include: Use of residual hearing (speaking clearly, hearing aids, or cochlear implants) or sight (signing within a restricted visual field, writing with large print)
The Lancet reported that untreated hearing loss in adults is the number one modifiable risk factor for dementia. [74] In 2017, a study also reported that adults using a cochlear implant had significantly improved cognitive outcomes including working memory, reaction time, and cognitive flexibility compared to people who were waiting to receive ...
Either hearing loss is a significant risk factor for driving and should prevent or limit people from driving, or it’s not a risk factor and deaf drivers shouldn’t face any additional hurdles ...
The shape of the plot reveals the degree and nature of hearing loss, distinguishing conductive hearing loss from other kinds of hearing loss. A conductive hearing loss is characterized by a difference of at least 15 decibels between the air conduction threshold and bone conduction threshold at the same frequency. On an audiogram, the "x ...
