Professional Audiology Clinic Ltd. deals with all manufacturers, thereby affording you with the best range of technology to suit your hearing needs. We fit all types and styles of hearing aids, and provide information about aural rehabilitation and general product care. We also offer cleaning and preventive maintenance services, and conduct minor repairs at our clinic.


Hearing Devices

A hearing device or hearing aid is an apparatus that typically fits inside or behind the wearer's ear and is designed to amplify incoming sounds for the wearer. They come in a wide range of styles offering choices that address individual hearing needs and accommodate personal preferences. 

Hearing Aids

Behind-the-ear (BTE)

BTE hearing devices fit behind the ear and provide sound to the ear through a tube, which connects to a custom-made earmold that sits inside the ear.  Sound is transmitted via air conduction.  BTE hearing devices can be used for mild to profound hearing losses.  Because of their durability and the ability to "grow" with the child (by changing the earmold as the child grows), along with their compatibility with assistive listening devices such as personal FM systems, BTE hearing devices are typically recommended for children. The devices come in a wide variety of colours, from inconspicuous skin tones to hair shades to bright hues.

Some BTE devices may also be "open-fit" devices, where a small plastic BTE case sits behind the ear with a small, fine, clear tube running into the ear canal. The device is secured in the ear canal by a dome or custom-made canal mold, leaving the ear more open and thereby reducing occlusion (but also increasing the possibility of feedback).  As well as being more open with less occlusion, because of the thin inner tube these devices are also more cosmetically appealing.

Man with Hearing Air

Receiver-in-the-ear (RITE)

RITE devices are similar to BTE devices, but the speaker (receiver) of the hearing device is placed inside the ear canal and a thin electrical wire replaces the acoustic tube of the BTE device. The benefits of RITE devices include smoother sounds with less distortion, smaller size and more cosmetic appeal, a more "open fit" (ear less plugged up), and less feedback.



ITE devices are custom made to fit in the outer ear bowl (called the concha). They can be used with mild to severe hearing losses.  For more severe losses, feedback (squealing or whistling caused by amplified sound leaking out of the device and being amplified again) can be a problem.  Because the receiver is inside the ear with these devices, they are susceptible to more problems or breakdowns due to wax build-up.


Half-shell (HS), In-the-canal (ITC), Mini-canal (MC), and Completely-in-the-canal (CIC)

HS devices are smaller than ITE devices, filling only the bottom half of the external ear.  ITC devices are smaller than HS, MC devices are smaller than ITC, and CIC devices are smaller than MC.  CIC devices are the smallest available and are not actually visible unless you look directly into the wearer's ear. These devices are intended for mild to moderately severe hearing losses. Their smallness, with the receiver of the hearing device sitting closer to the eardrum, is an advantage although they do not provide as much gain as the larger devices and are generally more occluding (because they block the ear canal). They are also more susceptible to problems or breakdowns caused by wax build-up and, because they run off the tiniest, they use up more batteries.

Hearing Protection

Hearing Protection

Noise exposure is a common, yet preventable, cause of hearing loss.  It is important to preserve one's hearing sensitivity.  Both the intensity of noise and the duration of time one is exposed to it determine how hazardous it is.  We have many types of hearing protection options available, including:

  • non-custom foam earplugs

  • non-custom HiFi noise defenders

  • custom solid industrial earplugs

  • custom filtered (ER-9, ER-15, and ER-25) musicians earplugs

  • custom floatable swimmers' earplugs

  • custom sleeper earmolds

  • custom digital hunting hearing protection

We can also provide custom communication molds, including:

  • custom earbud/radio earmolds

  • custom stethoscope adaptor earmolds

  • custom communications earmold (for reporters, law enforcement agencies, etc.)

  • custom telephone headset earmolds

  • custom pilot headset earmolds


Assistive Listening Devices (ALDs)

ALDs can help a person with a hearing loss or auditory processing disorder to hear better when in more difficult listening environments, such as a conference or classroom.  Alerting devices are also considered ALDs and are used to help alert people with hearing loss to doorbells, phones ringing, smoke detectors, babies crying, alarm clocks, etc.

Hearing Aid Loaner Bank – your recycle, refurbish, re-use opportunity!

Just like you we care about the future of our environment!  Whenever you are in the neighbourhood or coming to visit for an appointment bring in your old hearing aid batteries. We'll be happy to look after their proper disposal. 

If you have an older behind-the-ear hearing device that is no longer being used, please think about donating it to our Hearing Aid Loaner Bank. We refurbish these hearing aids and use them as loaners for patients whose hearing device is in for repairs, or to assist patients with financial and other special needs. Each donor will receive a free gift.
