Types and causes of hearing loss

There are many different types and causes of hearing loss, the most common being gradual Age Related Hearing Loss (ARHL). A very sudden loss in hearing (not related to the function of a hearing aid) is unusual and requires immediate medical treatment. Vertigo or dizziness which continues for more than a minute or two can indicate a condition affecting the inner ear, such as Menieres Disease.


This is the most common type of hearing loss, which affects the cochlea, situated in the inner ear.  Usually ARHL affects hearing in the higher frequencies, making speech sound less clear.  You can find more information on this here.


If you notice a very sudden loss of hearing, which you are sure is nothing to do with the function of your hearing aid, it is important to seek medical help within 24 hours from your local A&E hospital.


Menieres disease can cause a fluctuating hearing loss, dizziness and feeling of nausea. If you have experienced these symptoms, look at the NHS Menieres website for further information https://www.nhs.uk/conditions/menieres-disease/
