The different types of deafness

Hard of hearing 

There are people who can hear quite well, but may need a bit more volume or clarity. They may miss the occasional word or vowel which can lead to mistakes. Hearing aids are often helpful in quiet situations. They are often referred to: “hard of hearing”. Sometimes people will call themselves as “very deaf” when they have a lot of trouble hearing things. Medical people also use the term “hearing impaired” for this group as it is considered a more acceptable word than either deaf or hard of hearing.

Deafened 

This is often used to describe people who suddenly lose their hearing in adulthood. This could happen after illness or injury. The term “hearing impaired” or a person with “hearing loss” is also used for this group.

Partially hearing / deaf 

Traditionally education authorities have separated out children into different categories. This describes children who have quite a lot of useful hearing but still need a hearing aid or a cochlear implant to help them hear well. Many can use the telephone with people they know well (and often it will not be realised that partially hearing people can’t hear everything). Many people do not even realise that the partially hearing person can’t hear everything. 


Profoundly / severely deaf 

 These are two terms that education authorities have also used. They are used to describe children who are unable to understand speech sounds by listening. The latest cochlear implants are changing this and many children are now able to hear speech sounds so these two terms are now falling into disuse.


Cochlear Implantsprovide a sensation of hearing to people who have permanent, severe to profound deafness, and cannot hear the full range of speech sounds with standard hearing aids. A Cochlear Implant is different from a hearing aid. It has two parts: one is worn like a hearing aid, behind the ear or clipped on to clothing, and the other is surgically implanted.
