Hearing aid types and styles
Hearing aids come in a variety of types and styles. Finding the right one for you depends on your hearing loss and personal preferences.
In the market for new hearing aids? When comparing hearing aids, you'll quickly learn there are a variety of hearing aid options to help improve your hearing—choosing a hearing aid can feel overwhelming.
The best style of hearing aid for you depends on your type and degree of hearing loss, as well as the size and shape of your ear and your communication needs.
A note on over-the-counter hearing aids
The U.S. Food and Drug Administration recently approved the sale of over-the-counter (OTC) hearing aids. Although OTC hearing aids are not available in Canada, many Canadians have questions about what this means for their hearing healthcare.
OTC hearing aids in the U.S. generally have fewer choices and features than what Canadians can receive at their local hearing aid clinic.
When your hearing aids are professionally fitted by an audiologist, hearing instrument specialist or hearing aid practitioner, you have access to a wide range of types and styles, plus extensive hearing aid customization.
The basic components inside all hearing aids
A hearing aid is a small electronic device, housed in a plastic case, that contains:
All these parts come together to help you hear sounds you would struggle to hear otherwise, even in noisy environments and against background noise.
However, premium hearing aids may offer advanced features, including artificial intelligence and Bluetooth streaming.
There are two main types of hearing aids
Hearing aids can be divided into two categories based on the location of the processor: in-the-ear (ITE) and behind-the-ear (BTE). The best one for you is suitable for your hearing loss and lifestyle. You may prefer one with the latest technology, or a simpler model.
1. In-the-ear hearing aids
2. Behind-the-ear hearing aids
Let's take a look at the sub-categories of ITE and BTE hearing aids:
Half-shell and full-shell hearing aids
In-the-ear (ITE) hearing aids fill most or all of the outer ear canal opening.
There are two styles – a “half-shell” which fills the bottom portion of the ear opening, or a “full shell” which as expected, fills the whole opening.
The full-shell aids have more room on them to accommodate directional microphones and manual controls, such as a volume wheel or program button.
In-the-canal (ITC) hearing aids
In-the-canal (ITC) hearing aids sit in the canal portion of the ear. They are smaller and more discreet than the ITE style but still have space on the faceplate to accommodate directional microphones and manual controls.
Completely-in-canal (CIC) and invisible-in-canal (IIC) hearing aids
CIC and IIC aids are quite small and are fitted deeply into the ear canal. For this reason, they must be removed by using a removal cord. These styles are suitable for mild-to-moderate hearing losses. However, due to their small size, no directional microphones or manual controls are available, so sound quality may not be optimal.
Behind-the-ear with earmold
Traditional BTE aids are attached to a clear tubing and are fitted in the ear with a custom earmold. This earmold is made with an in-clinic impression by your hearing healthcare professional, just like a custom hearing aid.
BTE aids can fit any type of hearing loss, from mild to profound. Because their body is bigger and sits behind the ear, the device can house more features and larger batteries.
Children are typically fit with a BTE aid because of the programming flexibility and the fact that the earmold can be replaced as the child grows.
Open-fit aids (receiver in the canal or ear)
The RIC (receiver-in-canal) or RITE (receiver-in-the-ear) styles are also known as “open fit” aids. This style has a speaker wire and dome or mold that connects and sits in the ear.
This style is more discreet than a traditional BTE, and if the speaker wire gets damaged it is very easy to replace – without having to send the aid in for repair.
This style is now available as a rechargeable battery option. Because of how many features it offers, it is one of the most popular hearing aid styles on the market.
Which is the best hearing aid for me?
Now that we have reviewed the sizes and styles available, let’s talk about some further considerations for you in the decision making process:
Have you worn hearing aids before?
If so – are you satisfied with your current aid style and features? If so, then continue with them. If you are looking for something more up-to-date, or if your hearing levels have changed, it’s important to discuss this with your hearing healthcare professional.
How is your dexterity?
If you have difficulty handling small items or you lose feeling in your fingertips, it is generally advisable to avoid smaller devices, such as IIC. ITE or BTE aids with molds are easier to insert/control.
Generally, these aids have larger batteries (or rechargeable) which also means you would not need to change them as often as smaller batteries.
Hearing aids with automatic features are also a good idea, so that you don’t have to use tiny volume wheels or buttons to adjust the sound on your devices. Alternatively, some hearing aids are also available with a remote control.
What is your lifestyle like?
Are you a social butterfly or a homebody? If your daily activities are restricted or if there are cognitive impairments, ITE or BTE aids with molds may be the best option.
The ITE option is a self-contained unit making it easier to insert, and based on the larger size is easier to manipulate. A BTE aid with soft mold is also a good option, and both styles are simple for a caregiver to assist with.
If you are a social butterfly and tech savvy, the RIC style of aid may be more your speed. These aids are usually Bluetooth enabled, which allow you streaming from your phone or other wireless devices. The RIC style is slimmer than a standard BTE aid and quite discreet, and many are rechargeable, which streamlines the maintenance.
What is your hearing ability?
When you have your hearing tested, your hearing healthcare professional will review and explain your results.
If your hearing loss is fairly flat across all frequencies, a style that fills the ear canal with a mold or similar design would be appropriate to help amplify sounds across all pitches.
If your hearing loss is mainly in the high frequencies – which is more common due to aging or noise exposure – then the RIC style of aid would be most comfortable. These open-fit aids allow natural low-frequency sounds in while amplifying the high frequency sounds you are missing.
Hearing aids for profound hearing loss
If you have a severe to profound hearing loss, standard BTE aids with molds are advisable. These aids have the most powerful amplification and with the earmolds are least susceptible to moisture or wax damage in the ear canal.
They also come with advanced features like directional microphones, feedback suppression, adaptive noise reduction and the ability to pair with wireless devices or public systems.
In some cases, a cochlear implant may be the recommended treatment.
Hearing loss in one ear
If you have unilateral hearing loss (only one side) or an asymmetrical hearing loss (amount of loss is different on both sides), then a CROS or BiCROS system or bone anchored hearing system may be most suitable for you.
Find a hearing care professional
Ultimately, every person's hearing loss needs are unique. That's why a hearing care provider's knowledge and guidance can be invaluable. They can not only provide testing and fitting, they are up-to-date on the latest technologies, which improve all the time.
