Hearing loss can be temporary or permanent.  It often comes on gradually as you get older, but it can sometimes happen suddenly.

See your GP if you notice any problems with your hearing so you can find out the cause and get advice on treatment.

Signs and symptoms of hearing loss

It's not always easy to tell if you're losing your hearing.

Common signs include:

  • difficulty hearing other people clearly, and misunderstanding what they say, especially in noisy places
  • asking people to repeat themselves
  • listening to music or watching television loudly
  • having to concentrate hard to hear what other people are saying, which can be tiring or stressful

The signs can be slightly different if you only have hearing loss in one ear or if a young child has hearing loss.

When to get medical help

Your GP can help if you think you're losing your hearing.

  • If you or your child suddenly lose hearing (in one or both ears), call your GP or NHS 111 Wales as soon as possible.
  • If you think your or your child's hearing is getting gradually worse, make an appointment to see your GP.
  • If you're concerned about a friend's or family member's hearing, encourage them to see their GP.

Your GP will ask about your symptoms and look inside your ears using a small handheld torch with a magnifying lens. They can also do some simple checks of your hearing.

Causes of hearing loss

Hearing loss can have many different causes. For example:

  • Sudden hearing loss in one ear may be due to earwax, an ear infection, a perforated (burst) eardrum or Ménière's disease.
  • Sudden hearing loss in both ears may be due to damage from a very loud noise, or taking certain medicines that can affect hearing.
  • Gradual hearing loss in one ear may be due to something inside the ear, such as fluid (glue ear), a bony growth (otosclerosis) or a build-up of skin cells (cholesteatoma)
  • Gradual hearing loss in both ears is usually caused by ageing or exposure to loud noises over many years.

This may give you an idea of the reason for hearing loss – but make sure you see a GP to get a proper diagnosis. It might not always be possible to identify an obvious cause.

Treatments for hearing loss

Hearing loss sometimes gets better on its own, or may be treated with medicine or a simple procedure. For example, earwax can be sucked out, or softened with eardrops.

But other types – such as gradual hearing loss, which often happens as you get older – may be permanent. In these cases, treatment can help make the most of the remaining hearing. This may involve using:

  • hearing aids – several different types are available on the NHS or privately
  • implants – devices that are attached to your skull or placed deep inside your ear, if hearing aids aren't suitable
  • different ways of communicating – such as sign language or lip reading

Preventing hearing loss

It's not always possible to prevent hearing loss, but there are some simple things you can do to reduce the risk of damaging your hearing.

These include:

  • not having your television, radio or music on too loud
  • using headphones that block out more outside noise, instead of turning up the volume 
  • wearing ear protection (such as ear defenders) if you work in a noisy environment, such as a garage workshop or a building site; special vented earplugs that allow some noise in are also available for musicians
  • using ear protection at loud concerts and other events where there are high noise levels
  • not inserting objects into your or your children's ears – this includes fingers, cotton buds, cotton wool and tissues


Hearing loss is sometimes sudden, but more often it happens gradually and you may not notice it at first.

It can be temporary or permanent.  You may also have other symptoms, such as earache, unusual noises in your ear (tinnitus) or a spinning sensation (vertigo).

See your GP if you notice a problem with your hearing.  They can help work out what might be causing it.

General signs of hearing loss

It can be hard to tell if you're losing your hearing. Other people may notice it before you do.

Early signs of hearing loss include:

  • difficulty hearing other people clearly and misunderstanding what they say, especially in noisy places
  • asking people to repeat themselves
  • listening to music or watching TV with the volume higher than other people need
  • difficulty hearing on the phone
  • finding it hard to keep up with a conversation
  • feeling tired or stressed from having to concentrate while listening

These problems are often caused by hearing loss that can happen as you get older. This is permanent, but treatments such as hearing aids can help.

Signs of hearing loss in one ear

It's not always easy to tell if you've lost hearing in one ear, as you may still be able to hear with your other ear.

Signs of a hearing problem in one ear include:

  • your hearing is worse when sound comes from one side
  • all sounds seem generally quieter than usual
  • finding it hard to tell where sound is coming from
  • difficulty ignoring background noise or telling different sounds apart
  • finding speech unclear
  • difficulty hearing in noisy places or over long distances

Hearing loss in one ear is often caused by sound temporarily being unable to pass through the ear – for example, because of earwax or an ear infection.

Signs of hearing loss in children

our child may have a problem with their hearing if they:

  • are slow to learn to talk, or aren't clear when they speak 
  • don't reply when you call them
  • talk very loudly
  • ask you to repeat yourself or respond inappropriately to questions
  • turn up the volume of the TV very high

See your GP if you're worried about your child's hearing.

Hearing loss in children can be caused by a build-up of fluid in the ear (glue ear), which tends to get better over time and can be treated.

Signs of hearing loss in babies

Babies have a hearing check in the first few weeks after birth, but speak to your health visitor or see your GP if you think they might have difficulty hearing.

They may have a problem with their hearing if they:

  • aren't startled by loud noises
  • seem to hear some sounds but not others
  • notice you when they see you, but not when you call their name
  • don't turn towards voices by four months of age
  • haven't started to say any recognisable words by around 15 months


The treatments for hearing loss depend on what's causing it.

Sometimes it gets better on its own or can be treated with medicine or a simple procedure.  For example, earwax can be softened with eardrops or sucked out.

Other types of hearing loss - such as gradual hearing loss that can happen as you get older - may be permanent.

Hearing aids

Hearing aids are small electronic devices worn in your ear that make sound louder and clearer, although they won't give you back your full hearing.

There are many different types of hearing aid, including:

  • behind the ear hearing aids (most common type) - hearing aids that go around the top and back of the ear
  • in the ear hearing aids - small hearing aids that fit in the opening of the ear
  • in the canal hearing aids - very small hearing aids that fit a bit further into the opening of the ear, so they're just visable

Speak to your GP if you think you need a hearing aid.  They can refer you to a specialist who can advise you whether a hearing aid is suitable for you and which type is best.

Modern hearing aids are available on the NHS, but these are mainly the behind the ear type.  You can choose to pay privately for types not provided on the NHS.

Read more about hearing aids, including what the main types look like and how to get them on the NHS or privately.

Hearing implants

For some people, hearing aids don't help and instead they need to have a special device fitted inside or to their skull during an operation. These are known as hearing implants.

Common types of implant include bone anchored hearing aids, cochlear implants, auditory brainstem implants and middle ear implants.

Bone anchored hearing aids

A bone anchored hearing aid (BAHA) may be an option if you have hearing loss caused by sound being unable to reach your inner ear.

This type of hearing aid is attached to your skull during a minor operation. It picks up sound and sends it to the inner ear by vibrating the bones near your ear.

It can be clipped on and off – for example, it's removed at night and when you swim or take a shower. Some newer types are held onto the head with magnets instead of a connector through the skin.

Action on Hearing Loss has a leaflet about BAHAs and similar hearing aids (PDF, 360kb).

Cochlear implants

A cochlear implant may be an option if you have severe, permanent hearing loss that isn't helped by hearing aids. 

They work by turning sound into electrical signals and sending them to part of the inner ear called the cochlea. From here, the signals travel to the brain and are heard as sound.

The implant has two main parts:

  • a microphone behind the ear that picks up sound and changes it into electrical signals, which are sent along a wire to a device on the skin
  • a device placed inside the skull that picks up the electrical signals from the device on the skin and sends them along wires to the cochlea

Before having a cochlear implant, you'll have an assessment to find out if it will help. The implant will only work if the nerve that sends sound to the brain (auditory nerve) is working properly.

Action on Hearing Loss has more information about cochlear implants.

Auditory brainstem implants

An auditory brainstem implant (ABI) may be an option if you have severe, permanent hearing loss and a problem with your auditory nerve.

An ABI works in a similar way to a cochlear implant, but the electrical sound signals are sent directly to the brain along wires, instead of the cochlea.

An ABI won't usually fully restore your hearing, but it can usually improve it to some degree.

Hearing Link has more information about auditory brainstem implants.

Middle ear implants

A middle ear implant (MEI) may be an option if you can't use a regular hearing aid – for example, because you're allergic to the materials they're made from or they don't fit in your ear correctly.

An MEI has two main parts:

  • a device attached to the skin that picks up sound and turns it into an electrical signal
  • a device under the skin that picks up these signals and sends them along a wire to the small hearing bones deep in the ear, which causes them to vibrate

Vibrating the hearing bones means that sound can travel into your inner ear and brain. This won't fully restore your hearing, but it can help make sounds louder and clearer.

Hearing Link has more information about middle ear implants.

Sign language and lip reading

If you've been deaf from birth or you develop severe hearing loss later in life, it can affect your ability to communicate with other people.

But you can learn different methods of communicating that can be used instead of, or as well as, spoken English.

Two of the main methods are:

  • lip-reading – where you learn to watch a person's mouth movements while they're speaking to understand what they're saying
  • sign language – a visual way of communicating using hand gestures, facial expressions and body language
