Hearing loss

Also called Deafness or Hard of hearing

Hearing loss is very common, especially as people get older. It can come on gradually or suddenly and affect one or both ears. Causes include ageing, loud noise, earwax, ear infections, glue ear and some medicines. Sometimes it is permanent and sometimes it can be treated.

What it is

Earwax and infections can usually be treated. Age-related and noise-related hearing loss is permanent, but hearing aids or cochlear implants can help a lot.

Protecting your ears from loud noise helps prevent it.

Common signs

  • Difficulty hearing other people clearly
  • Asking people to repeat themselves
  • Turning the TV up loud
  • Finding it hard to follow conversations in noisy places
  • Ringing in the ears

How it is usually diagnosed

  • Examination of the ears
  • Hearing tests (audiometry)
  • Scans, sometimes

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Audiograms over time
  • ENT and audiology letters
  • Hearing aid details and settings

Questions to ask your doctor

  • What type of hearing loss do I have?
  • Would a hearing aid help?
  • How often should my hearing be checked?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Sudden hearing loss in one or both ears: get seen the same day, early treatment can help
