Hearing Aids and Types of Hearing Aids

Alta2_family

A hearing aid is a personlised device. It is tailored made for your degree of hearing loss, shape of your ear and in many cases, your listening preferences. And today, hearing aids are available in a wide range of features, styles, colours, and sizes.

  1. Microphone: receives the sound in the environment, and coverts the sound to the electronic signals.
  2. Amplifier: amplifies sound signals. In a digital hearing aid, it resembles the processor of a computer, so different sound signals can be transmitted in its best quality possible.
  3. Receiver / Speaker: reconverts the amplified / processed signals to audible sounds.
  4. Battery: provides power to the hearing aid

Why 2 Hearing Aids are Better Than 1

Being able to hear with both ears is just as important as being able to see with both eyes. If you have difficulty hearing with both ears, it is quite certain that you will be benefited from binaural fitting — wearing a hearing aid in each ear.

The major benefits of binaural fitting are:

  • Better localisation of sounds
  • Easier understand of speech in noisy surroundings
  • Lower risk of auditory deprivation
  • Enhanced sound quality

Type of Hearing Aids

Type Degree of Hearing Loss Description
BTE
BTE
(Behind-the-Ear)
Mild to Profound It is worn behind the ear, and it has the most sound output among all hearing aids.

Mini RITE
(Receive-in-the-Ear)
Mild to Severe The receiver is placed in the ear canal instead of the body of the hearing instrument, therefore the size is much smaller than a traditional BTE.
ITE
ITE
(In-the-Ear)
Mild to Severe The shell of the instrument is custom-made, and the entire hearing aid is placed in the ear. It is relatively smaller than BTE
CIC
CIC
(Completely-in-the-Canal)
Mild to Moderate The hearing aid is placed completely in the ear canal, and is the most invisible amongst all hearing aids.
