What is a Hearing Aid?

Hearing aids are small electronic devices fit uniquely to an individual's hearing loss. They contain microphones, which allow them to pick up sounds to be processed by a microchip.

Manufacturers spend millions of dollars on research and development creating the microchips, which enable hearing aids to suppress ambient noise and make speech clear, natural and audible to the patient. The receiver is the part of the hearing aid that goes into the ear and projects the sound.


Advancements in hearing aid technology mean patients now have more options when selecting a hearing aid with their audiologist.

Custom Hearing Aids

Invisible in the Canal (IIC)

The IIC is the smallest custom made hearing aid available, fitting deep in the ear canal. They are suitable for mild-to-moderate hearing losses, and are completely invisible in most ears. An audiologist can inform you if this is a suitable option.


Completely in the Canal (CIC)

The CIC model is small, fitting directly into the ear canal, but is not seated as deeply as the IIC. They are discrete and fit mild to moderately-severe hearing losses.

In the Canal (ITC)

The ITC model is seated in the canal, with a portion of the hearing aid exposed in the outer ear. They can typically accommodate severe hearing losses, but may not be suitable for those with small or narrow ear canals.

In The Ear (ITE)

The ITE model fills the entire outer ear bowl and is suitable for mild to severe losses. This style is easy to insert and a suitable option for those with poor dexterity.

Behind the Ear Hearing Aids

Behind the Ear (BTE)

There are two parts to this model: the hearing aid, which sits behind the ear and the ear mold, which sits in the ear. The mold is connected to the hearing aid via a tube. This style suits all degrees of hearing loss, and is great for individuals with poor dexterity and vision.


Receiver in the Canal (RIC)

This style of hearing aid is the most popular. It is comfortable, discrete, easy to insert, and fits mild to severe hearing losses. The microphone is housed in the body of the aid, however, the speaker sits in the ear canal.
