The structure of a hearing aid

Hearing aids come in different sizes, levels of application, ease of handling, volume control and availability of special features. A hearing aid will be dependent on the nature and severity of hearing loss and the dexterity of the user.

Mutual components of a hearing aid are as follows:

  • Microphone: A microphone picks up external sounds.
  • Amplifier: This makes sounds louder.
  • Receiver: Delivers amplified sound into the ear.
  • On and off switch
  • Battery pack
  • Earmolds or Earpieces: Direct the flow of sound into the ear and enhance sound quality. 

Your hearing aid

If you choose to wear hearing aids, the following will happen:

  • You will be offered a choice of colour to choose from (see picture below)
  • We will advise which style of hearing aid suits your clinical and physical requirements
  • We will organise an ear impression, if needed
  • We will book a fitting appointment.
