Caring for Clients With Hearing Loss


Published: 22 September 2020

Hearing loss is highly prevalent in older adults, especially those who are living in residential aged care (Deafness Forum of Australia 2018).

In Australia, about 14% of the population has a hearing disorder and over 70% of people over the age of 70 have hearing loss. Approximately 15% of Australians use hearing aids (AIHW 2016; Deafness Forum of Australia 2018).

Given these statistics, you are likely to encounter clients who have hearing impairments and use hearing aids, especially when caring for older adults.

It is important to know how to care for these clients and ensure that hearing aids are being used appropriately.

Understanding Hearing Loss

Hearing loss is the reduction of a person’s ability to hear. This is often caused by wear and tear to the hairs or nerve cells in the cochlea over time from ageing and chronic exposure to loud noise, which impairs the electrical signals being transmitted to the brain. Gradual hearing loss caused by age is known as presbycusis (Mayo Clinic 2019a).

Other causes of hearing loss include:

  • Congenital causes (can be hereditary or non-hereditary);
  • Infectious diseases (e.g. measles, meningitis and mumps);
  • Chronic ear infections;
  • Fluid in the ear;
  • Head or ear injury; and
  • Wax or foreign bodies in the ear canal.

(WHO 2020)

Presbycusis is a type of sensorineural hearing loss, meaning it is caused by damage to the hearing organ, cochlea or auditory nerve. This type of hearing loss is generally irreversible (Healthdirect 2020).

Other types of hearing loss include:

  • Auditory processing disorders, which are caused by the inability of the brain to process sound normally.
  • Conductive hearing loss, where problems in the outer or middle ear (e.g. earwax build-up, infection, fluid) prevent sound from reaching the inner ear. This type of hearing loss can generally be resolved.
  • Mixed hearing loss, which is a nomination of sensorineural hearing loss and conductive hearing loss.

(Healthdirect 2020)

People who have mild to severe hearing loss are considered to be ‘hard of hearing’. People who are deaf usually have profound hearing loss (very little or no hearing) (WHO 2020).

Barriers to Addressing Hearing Loss

On average, people who use hearing aids have taken 10 years to seek help for their hearing loss (John Hopkins Medicine 2014). Furthermore, it is estimated that only 17% of people who could benefit from a hearing aid are actually using one (WHO 2020).

Barriers that may prevent people from addressing hearing loss include cost, perceived difficulty of using hearing aids and unwillingness to accept ageing (John Hopkins Medicine 2014).

Some people may have difficulty noticing their hearing loss in the first place because it tends to occur gradually (Hearing Australia 2019a).

Even if healthcare staff recognise the signs of hearing loss, they may misdiagnose it as dementia or a mental health condition due to the ambiguity of certain symptoms (e.g. unresponsiveness and confusion) (Action on Hearing Loss 2020).

Being able to correctly identify the signs of hearing loss is essential, as early detection is crucial for better client outcomes and the fitting of hearing aids (Action on Hearing Loss 2020).

Recognising Hearing Loss in Clients

The following signs might indicate that a client is experiencing hearing loss:

  • Often asking people to repeat themselves;
  • Watching television at a loud volume;
  • Ringing or buzzing in their ears (tinnitus);
  • Straining to hear;
  • Not hearing everyday sounds (e.g. doorbells and phones);
  • Difficulty hearing in noisy environments;
  • Difficulty hearing and understanding conversations;
  • Speaking either very softly or very loudly; and
  • Withdrawing from social interactions.

(Hearing Australia 2019a; Healthdirect 2020; Davies 2019)

It is important to note that high-frequency sounds are generally the first to be affected by hearing loss (Hearing Australia 2019b).

Older adults should undergo a hearing test every 12 months and be referred to a specialist immediately if hearing loss is identified (Hearing Australia 2019b).

The Impacts of Hearing Loss

People with hearing loss may experience loneliness and isolation.

Hearing loss has been associated with:

  • Impaired ability to communicate with others;
  • Loneliness;
  • Isolation;
  • Frustration;
  • Depression;
  • Anxiety;
  • Cardiovascular disease, stroke and obesity;
  • Cognitive impairment and decline; and
  • An overall decrease in quality of life.

(WHO 2020; Mayo Clinic 2019a; Action on Hearing Loss 2020)

What are Hearing Aids?

Hearing aids are electronic devices that increase the volume of sounds, allowing people with hearing loss to hear more easily. They work by receiving sound waves through a microphone and converting them into electrical signals. These signals are then amplified in power and transmitted to the ear using a speaker (NIDCD 2017).

Hearing aids come in a variety of styles:

  • Behind the Ear (BTE) hearing aids consist of a case that fits behind the ear (containing all the electronic components) and an ear mould that connects to the case via a tube.
  • Receiver in canal (RIC) hearing aids consist of a sound processor behind the ear, connected to a receiver that sits inside the ear canal.
  • In-the-ear hearing aids are custom-made to fit the client’s ear. They include:
    • In-the-ear (ITE) hearing aids, which fit in the outer ear.
    • In-the-canal (ITC) hearing aids, which fit partially inside the ear canal.
    • Completely in canal (CIC) hearing aids, which fit entirely inside the ear canal.

(NIDCD 2017; Hearing Australia 2019c, n.d.; Mayo Clinic 2019b)

Working with Hearing Aids

Some clients may need assistance with inserting, removing, cleaning and troubleshooting their hearing aids. It is important that you know how to perform these tasks so that you are able to help them if required (Deafness Forum of Australia 2019).

Inserting a Hearing Aid

  1. Perform hand hygiene.
  2. Wipe the aid with a tissue, brushing away any earwax. You may need to use the client’s wax cleaning tool to pick wax out of the ear mould.
  3. Close the battery casing and ensure the aid whistles when you cup your hand around it.
  4. Carefully insert the hearing aid into the correct ear (the left aid should have a blue dot and the right aid should have a red dot). It should fit inside snugly.
  5. If the client is using a BTE hearing aid, ensure the tubing is not pinched or twisted.
  6. Using your normal voice, ask the client two straightforward questions to assess whether the volume is set to an appropriate level.

Removing a Hearing Aid

  1. Use your thumbnail to open the battery casing.
  2. Gently remove the hearing aid and store it appropriately.
  3. The hearing aid should be stored with the battery door partially open and battery inside the casing.

(Deafness Forum of Australia 2019)

Changing a Hearing Aid Battery

  1. Use your thumbnail to open the battery casing.
  2. Use the magnetic tip of the client’s wax brush to lift the battery out.
  3. Discard the battery.
  4. Check the size and expiry date of the new battery.
  5. Insert the new battery into the casing with the flat side facing upwards.
  6. Close the battery casing and ensure the aid whistles when you cup your hand around it.

Potential Issues With Hearing Aids

When inserting, removing or cleaning a hearing aid, you may experience issues such as:

  • The client not hearing any sound;
  • The client hearing whistling;
  • Weak sound;
  • Wax build-up;
  • Lost or failed batteries.

Practical Tips for Caring for Clients With Hearing Loss

  • Encourage clients to wear their prescribed hearing aids.
  • Ensure clients’ hearing aids are switched on, properly inserted and have working batteries.
  • Hearing aids should be cleaned daily.
  • Hearing aid batteries should be changed weekly.
  • Ensure clients’ hearing aids are kept in a familiar and easily accessible place.
  • Ensure hearing aids are kept away from heat and moisture.
  • Hearing aids should always be removed before the client showers or uses an electric razor to shave their face.
  • Do not use hair dryers or hairsprays near a hearing aid.
  • Try to minimise background noise in communal areas, and ensure there are quiet areas without televisions etc. where clients can have conversations.
  • When a client first begins to use a hearing aid, the volume should initially be set low and gradually increased to a comfortable level.
  • Refer clients to a specialist if you suspect earwax build-up.
  • If you suspect an issue with a client’s hearing aid, contact their audiology specialist.
  • Take note if a client is frequently adjusting their hearing aid, as this may indicate an issue.
