Hearing Aids

Hearing aids are an extremely popular solution for people affected by hearing loss. Research has identified a number of benefits from hearing aid use, including:

  • Enhanced communication abilities
  • Higher levels of self esteem
  • Improved personal safety
  • Higher quality of life
  • Better psychological health

Choosing a device

When selecting a hearing aids it’s important to consider a number of factors. NHC clinicians will work with you to choose a device that suits your specific needs and budget. Before choosing a suitable hearing aid, the following factors must be considered:

  • Your lifestyle (e.g. home and work environment, physical activity)
  • The degree and type of your hearing loss
  • The specific situations in which you experience difficulty
  • Your budget

NHC clinicians will ensure that your aid is fitted and adjusted so that you enjoy maximum comfort and benefit from your device.

Hearing Technology

When selecting a hearing aid, technology is one of the most important considerations.  Below is a summary of different types of available technologies. Most are available in different levels of sophistication. For specific details and to understand which features would best benefit you, speak to your National Hearing Care clinician.

Sound quality

Your clinician will be able to adapt the amplification profile to give you the best possible sound quality.  In addition, the following features can help manage sound quality:

  • Volume control changes (including data learning features)
  • Feedback management systems

Speech Intelligibility

The only proven way to improve speech intelligibility in background noise is through the use of directional microphones.

Directional microphones are available in different levels of sophistication ranging from:

  • Fixed directional (always reduces noise in a given area) 
  • Binaurally coordinated automatically adaptive directional microphones that adapt to the individual's environment

Noise Reduction

Noise comes in various forms. To help reduce the annoyance hearing aids may act to reduce
the following noise types:

  • Wind noise 
  • Background noise (such as restaurant noise)
  • Sudden loud noises (e.g. a door slamming)
  • Low level noise (generated from the hearing aid itself)

Ease of Use

Features that help the hearing device easily adapt to different environments are: 

  • Binaural Coordination
  • Data Learning
  • Environmental Classification
  • Automatic volume controls 
  • Remote Controls
  • Telecoils

Hearing Device Styles

There are five distinct styles of hearin​g aids that vary in size. Some are m​ore appropriate for certain types of hearing loss and ear shapes, and others have more technological features.  Your NHC Clinician will be able to advise which style will work with your hearing loss. Here are the main styles available:

Receiver "In The Ear"

These popular devices have replaced the conducting tube with an electrical wire connected to a miniature speaker in the ear canal.

Open Fit "Behind The Ear"

This style of hearing device is one of the most often prescribed. Due to the design, it provides a more natural sound that the brain can recognise.

"Behind The Ear"

This style sits behind the ear and sounds are channeled via a tube attached to a custom-made mould that sits in the ear canal.

"In The Ear"

These devices sit inside the ear and can be easier to manage for people with limited dexterity.

"Invisible In The Canal"

"Invisible in the Canal" devices are suitable for mild to moderate hearing loss. Due to their size, they're not suitable for all ears.

Why Two Ears?

There are many benefits to having two ears operating together including:

  • Sound localization (especially important when danger is around)
  • To help pick out speech in noise

The most common causes of hearing loss affect both
ears fairly equally, so in most cases we advise getting
hearing aids for both ears.  If you decide to only amplify one ear
then you are compromising on sound quality,
your ability to localize sound,and not giving your
brain the best chance to readapt to sound.

There is evidence to show that it can
have a long-term effect on your
hearing ability if you don't aid
both ears together.


When you are first fitted with a hearing device, you might hear a little too much!  This is because you have adjusted over time to having less hearing. It takes time to adjust to hearing devices—restoring lost hearing is a slower process than vision restoration as the brain needs to be retrained to adapt to the new levels of sound.

A little persistence goes a long way

The more you wear your hearing devices, the more sounds you will hear.  And these will gradually become part of your everyday life. To help support you on this journey, we at National Hearing Care have implemented an acclimatisation program that we all encourage our clients to participate in so that they can gradually get used to their hearing devices.
