Hearing services available to help your child

A range of hearing services teams are available to help your child.

Paediatric audiology team

Audiologists are healthcare professionals who identify and treat hearing problems. 

Your child’s audiologists will do the following:

  • Measure your child’s hearing levels and test how much hearing your child has.
  • Explain the different types of hearing tests available so they can help your child hear as well as possible.
  • Prescribe personal hearing aids, sound processors and other listening equipment.
  • Give advice on how you can encourage your child to wear hearing aids.
  • Show you how to care for your child’s hearing aids.
  • Offer advice on how to change your child’s everyday environment so they can hear better.
  • They may refer your child to specialist services, for example to a Cochlear Implant Centre.  They will discuss this with you first.
Your child’s paediatric audiologists are:

Types of hearing loss

The audiogram below can help you understand your child’s level of hearing.

Audiogram of familiar sounds

Audiogram of familiar sounds

May have difficulty hearing quiet or distant voices.

Likely to experience some difficulty in communication and education settings and become easily tired. 

An increased sound volume will help them to hear better.

Can often understand conversational speech when facing the speaker and being close to the speaker.

Can miss 50% or more of the speech signal if they do not use a hearing aid.

Will need to use hearing aids. They may require extra support in school, for example a radio aid or a better choice of seating and lighting. 

A radio aid is an assistive listening device. It will help them cope with noise in the classroom.  It will also help them cope with being far away from the person speaking in the classroom. 

Can only hear conversation when it is loud.

Can miss up to 100% of speech information if they do not wear a hearing aid.

Can hear a normal conversational voice if they use a correctly programmed hearing aid.

Will benefit from extra help in school (for example a radio aid or a better choice of seating and lighting. 

Will benefit a great deal from using a radio aid all the time.

May be able to hear extra loud voices if they are close to the people speaking.

Will need to use hearing aids to hear conversational speech and environmental sounds.

Will benefit from a radio aid.

Will need to wear appropriate technology to make sounds louder.  For example hearing aids, a cochlear implant or a radio aid can help them hear conversational speech.

Will benefit from a radio aid and extra help at school (for example visual cues and preferential seating).

Speak to your paediatric audiologist if you want more information on radio aids and how they can help your child.

Hearing aids and children

How can a hearing aid help my child?

A hearing aid is a system that makes all sounds louder.  It does not give your child the ability to hear fully, but it does make the most of their existing hearing ability.

Some sounds and speech will not always be clear and may sound different.
Your child will probably notice many sounds that they have not heard for a while.
The more your child gets used to using a hearing aid system, the more sounds they will learn to recognise and accept. 

Willingness to wear a hearing aid

Sometimes a child prefers not to wear a hearing aid. There are many reasons for this. The most common are:

  • Sounds feel unfamiliar and frightening, or too loud.
  • They don’t like having something in their ear canal.
  • They feel embarrassed or self-conscious about wearing it.
  • The earmould is uncomfortable.
  • The hearing aid does not fit comfortably behind the ear.

How can I help my child get used to wearing a hearing aid?

The more your child gets used to using a hearing aid system, the more sounds they will learn to recognise and accept. 

  • Your child’s age, and the extent of their hearing loss, will determine how often they need to wear the hearing aid.
  • We recommend you gradually introduce your child’s hearing aid use into everyday activities.
  • They can use it at home for the first few weeks.
  • They can gradually start wearing it at school and in the outside world.
  • Most children wear their hearing aids all day. A few children only wear them in certain situations, for example at school.

How can I tell if my child’s hearing aid is helping them to hear better?

Children do not always express themselves and tell us how well or poorly a hearing aid is working.

Your observations will help us to adjust your child’s hearing aid(s) when needed.

  • Watch how your child acts when they use the hearing aid(s).
  • Talk about your observations with your partner or other adults.
  • Remember things may change as your child gets used to the hearing aid(s).
  • A few days before your child’s next appointment, make a list of your observations.  You may want to discuss them with the audiologist. 

How to use your hearing aid

Follow the instructions in the tables below.

Turning your hearing aid on and off

To switch the hearing aid on, close the battery compartment.
Turning on the hearing aid
To switch the hearing aid off open the battery compartment. Do this when you are not using the hearing aid, to save battery life.
Turning off the hearing aid

Removing and replacing the battery

Open the battery compartment using your finger.Turning off the hearing aid
Usually the battery drops out when the compartment is completely open.
If the battery does not come out, lightly tap the instrument.
Do not use a pen or similar as this may damage the hearing aid.
Replacing the battery
Insert the correct size battery.
(Your paediatric audiologist will tell you which kind of battery you need when the hearing aid is fitted).
Make sure that the + symbol on the battery points upwards.
Correct battery insertion
Close the battery compartment.
Do not force the door shut. If it does not close easily, check to see that the battery has been inserted correctly.
When the battery door is completely closed, your hearing aid is ready for use.
Turning on the hearing aid

Removing and replacing the battery on a hearing aid with a tamper proof battery door

If your child or their sibling(s) are younger than 5 years of age, we will fit a tamperproof battery door to your child’s hearing aid. This will prevent a young child from accessing the battery. 

Open the tamper proof battery compartment using the plastic tool. Change the battery as described above (see Removing and replacing the battery).Opening the tamper proof battery door

Hearing aid battery safety

Children under 5 years old

  • Try not to let young children watch when you change the batteries.
  • It is safer if they do not know how to open the battery compartment.
  • Hearing aids for children under 5 years of age usually have tamper proof (childproof) battery lock. We will give you a small plastic tool to unlock the tamper proof battery door.
  • These tamper proof battery locks are especially useful if your child has brothers or sisters, or if they are cared for with children who are younger than 5 years old.

If you are not sure, ask your audiologist whether your child’s hearing aid has a childproof battery lock.

Children over 5 years old

Speak to your audiologist if your child is over 5 years old and you feel they may benefit from a tamper proof battery lock.

What do I do if my child swallows a battery?

If your child swallows a battery, immediately contact your nearest Emergency Department (A&E). 

Tell them what type of battery your child has swallowed and approximately when they swallowed it.

Take a similar battery and the packaging with you to the Emergency Department (A&E) so hospital staff can identify the type of battery.  This will help them decide what action they need to take.

Young children can also get small batteries stuck in their nose and ears.  Sometimes this goes undetected until they develop ulcers or tissue damage.

Always keep a check on the number of batteries that you have at home.

Contact your nearest Emergency Department (A&E) if your child swallows a battery.

How do I safely dispose of used batteries?

Get rid of used batteries carefully as they contain chemicals that can be harmful.  You can:

  • Safely dispose of them in your normal household rubbish bags.
  • Take them to your local recycling centre (check with your local council before you go).
  • Take them to local supermarkets if they offer a recycling box for used batteries.  Check before you go.

Hearing aid maintenance

Cleaning the earmoulds

Detach the earmould from the hearing aid.
To do this squeeze the tubing near the hearing aid and pull the aid from the tubing.
Cleaning the earmould
Leave the earmould in a solution of warm soapy water for 30 minutes.
Use a safety pin or a sewing pin to remove any wax that is blocking the earmould. 
Run warm water over and through the earmould to clear the soap.
Washing the earmould
Dry the earmould with a tissue or kitchen paper. 
Blow through the tubing to ensure no water is left in the tubing.  (Water left in the tubing will damage the aid when it is reattached.)

If you have been given a puffer, pop it in the end of the tubing and give it a blow. This will dry out any water or condensation which has built up in the tubing.
Drying the earmould
Reattach the earmould to the hearing aid by squeezing the tube.Reattaching the earmould to the hearing aid
Ensure the earmould and hearing aid are connected correctly.
Fit them together correctly by placing the earmould curve to the inside of the curve of the hearing instrument.
Connecting the earmould and hearing aid
The picture shows the left side correctly connected.Left side connected.
The picture shows the right side correctly connected.Right side connected

Remember to make sure your hearing aids never get wet .

Retubing the earmould

You will need to change the tubing when it begins to harden, changes colour or splits.

Your audiologist will show you how to change the tubing.  You can also take it to a hearing aid repair session run by the audiology department.

Step 1
Pull the old tubing out of the earmould.
Do not throw the old tubing away as you will need it later.
Earmould retubing
Step 2
Cut the last 5cm (2 inches) of a piece of pre bent tube to a tapered end.
Thread this through the earmould until it comes out the other end.
Cut the pre bent tube
Step 3
Pull the tube until the bend reaches the earmould.
All the tapered section should have come through the other side.
Pull tube through
Step 4
Cut the tapered tubing as close as possible to the earmould to avoid any rough edges that might be uncomfortable in the ear. 
(Any tube sticking out could rub your ear and make it sore.)
Cut the tapered tubing
Step 5
Take the old piece of tubing you saved and line it up with the newly threaded tube. Cut the end to the same length.
Line up the old tubing
Step 6
Push the end of the tubing onto the plastic nozzle of your hearing aid.
Make sure that it bends in the right direction.
Reattaching the tubing

Moving over to adult audiology services

This section is for teenagers and young adults who are about to start moving over to the adult audiology service.

It prepares you for the adult audiology service and supports you through the move from secondary school to university or employment.
