Invisible Hearing Aids

What are Invisible Hearing Aids?

Invisible hearing aids are the perfect solution for those in Australia who want a discreet and small hearing aid for mild-to-moderate hearing loss. If you’re located in Melbourne, you’ll be happy to know that invisible hearing aids are available in your area too. Hearing aids have come a long way in Australia. Today’s smallest hearing aids are comfortable, inconspicuous and sophisticated digital devices that vary in size, colour, special features and the way they are fitted in your ears. And importantly to some users, many of these small hearing aids in Australia are virtually invisible, making them perfect for pensioners and seniors who want to keep their hearing aids discreet.

Invisible hearing aids are the smallest type of hearing aids and are placed very deep inside the ear, making them invisible to the naked eye. This type of hearing aid provides superior sound localisation, as the microphone is so deep in the ear canal that the wearer is able to benefit from the natural shape of the outer ear. For those who are interested in extended wear, there are invisible extended wear hearing aids, such as the Phonak Lyric hearing device which can be worn 24/7 with no need for daily insertion, removal, or battery change.

They normally utilize the most cutting-edge digital technology, work fully automatically, and are in sync with other technologies including smartphones. There are 2 types of invisible hearing aids currently available: daily-wear devices called Invisible In The Canal (IIC) and the extended-wear type called Invisible Lyric.

Benefits of Invisible Hearing Aids

They’re invisible!

Invisible In The Canal (IIC) hearing aids are popular in Australia because they are essentially invisible. Although there are a wide range of In The Ear (ITE) hearing aids available on the market, IICs are the smallest and fit the furthest down in the ear canal, making them well hidden and virtually undetectable. If you are concerned with the appearance of Behind The Ear (BTE) hearing aids, IICs are a good option that give you the benefit of hearing aids without advertising to the world that you’re wearing them.

Feel more natural

IICs can improve how you hear your own voice while wearing them, allowing for a more natural hearing experience. Often, when people wear hearing aids that fill a significant portion of their ear canal, they report that their own voice is too loud or that sounds have a hollow quality to them. This is called the occlusion effect and happens when low pitch sounds (like your voice coming from inside your head) get ‘trapped’ in the ear canal between the eardrum and the hearing aid, which can create discomfort and distorted sounds.

IICs help to reduce the occlusion effect in two ways. First, they sit much deeper than other aids so a smaller portion of your ear is covered, creating less internal vibration and less unnatural sound distortion. Second, IICs are typically much shorter than other ITE devices, making it easier to release or ‘vent’ the low pitch sound waves to the outer ear, causing less occlusion discomfort.

Natural sound quality

For many users IICs provide a more natural sound quality, which makes it easier to adjust to wearing hearing aids. Because IICs are placed deep in the ear canal, the natural cues from the sound interacting with the shape of your ear are preserved. There are no wires or tubes getting in the way, and they don’t block your ear, allowing sound to enter your ear naturally. As an added benefit, the placement of IICs may increase your ability to localize/determine where sounds are coming from.

Limitations of Invisible Hearing Aids

They lack advanced directionality and Bluetooth connectivity

A disadvantage of IIC hearing aids is that they’re too small to fit more than one microphone, making directional features impossible to support. The limited size also makes it difficult for some advanced features – like Bluetooth connectivity – to be built in.

They may not be strong enough for people with severe hearing losses

IICs are most beneficial for individuals with mild or moderate hearing loss. Because they’re so small, there just isn’t enough room on the hearing aid for more advanced technology like powerful speakers and stronger processing power. So IICs are not recommended for people with very severe or profound hearing loss.


They have a short battery life

Because of their size, these aids use smaller batteries that need to be replaced more often than those in larger hearing aids, which can become costly.

IIC’s aren’t for all ears

If your ear canal is too small or shaped in such a way that the IIC device cannot be placed in the right area, an invisible hearing aid may not be an option. Also, if you have vision or dexterity problems and can’t reliably place the hearing aid in the right position, you’ll get less of a benefit from the aid. Additionally, IIC’s may not be a good option for people with constant ear wax build-up, as the ear wax can block the microphone and speaker, thereby reducing the hearing aid reliability.

Are Invisible Hearing Aids Right for you?

Invisible hearing aids, such as IICs, are an excellent choice for many individuals in Australia, especially those with mild-to-moderate hearing loss who want a discreet device.
