Hearing aid technology in Australia has come a long way — today’s modern hearing aid devices offer incredibly realistic sound quality and advanced features that can dramatically increase the quality of life of someone with hearing issues.
Among the most popular types of new hearing aid devices are invisible hearing aids which are the smallest version of hearing aids on the market. When worn, invisible hearing aid models are virtually undetectable – ideal for individuals who need a discreet option for hearing aids.
How Do Invisible Hearing Aids Work?
Invisible hearing aids also referred to as invisible-in-the-canal (IIC) hearing aids, are small-sized hearing aid devices that are designed to sit deep inside the ear canal – to the point that they are almost completely hidden from view (that’s right, almost invisible!). Invisible hearing aid devices can be as small as 2.5 cm in length.
Invisible hearing aids function in the same way that most types of hearing aids do. Once worn, the built-in microphone receives sound waves that travel to the ear, which are converted into electronic signals that are replicated by the amplifier and the device speaker to the parts of the inner ear.
Features & Benefits of Invisible Hearing Aids
Virtually invisible
The standout feature of invisible hearing aids is that they are inconspicuous when worn — compared to in-the-ear (ITE) or behind-the-ear (BTE) hearing aid models, they are placed the furthest down the ear canal, which keeps them hidden from almost all angles of viewing.
This feature is especially favoured for those who want to be discreet about their need for hearing aids.
Less sound distortion
A side effect of wearing hearing aid devices is the occlusion effect. Due to the space in the ear that is taken up by worn hearing aids, there can be a bit of a a distortion when low-pitch sounds (such as the wearer’s own voice) resonate between the eardrum and the hearing aid in the ear canal.
Invisible hearing aids minimise the occlusion effect, simply because they are worn more deeply in the ear. It means that there’s less space for lower-frequency sounds to get trapped in the ear. Invisible hearing aids ar also much smaller than other ITE devices, allowing the devices to release low-pitched sounds outside of the ear, resulting in less listening distortion.
More natural sound quality
The entire shape of the ear lobe contributes to the way sounds are heard, which means that larger or bulky hearing aid models change the natural sound quality for users.
As invisible hearing aids are placed deep in the ear canal, the natural shape of the outer ear is unaffected, leading to a more authentic and realistic sound quality, similar to what would be heard naturally. IICs also have no extending wires or parts that block sound waves, which allows sound to enter the ear naturally.
Considerations for Invisible Hearing Aids
Limited connectivity and control features
The small size of invisible hearing aids means that devices can be limited with connectivity features like Bluetooth, directional microphones, etc.
The placement of invisible hearing aids deep in the ear also means there’s a lack of physical control features (volume, program changes) on the device. Users will have to access these control settings via a smartphone app or a remote control.
May not be suitable for severe hearing loss
Invisible hearing aids can deliver crystal clear sound quality, but the small build means they may not be appropriate for those with severe hearing loss. As such, invisible hearing aids are usually recommended for individuals with mild or moderate hearing loss.
Shorter battery life
Invisible hearing aids are typically equipped with smaller-capacity batteries, which can require more frequent replacement or recharging compared to other larger hearing aid models.
Specialised fit required
An invisible hearing aid device may not be an option if your ear canal is too small or shaped in a way that prevents proper placement. Individuals who struggle with vision or dexterity may also find it hard to place the hearing aid correctly, leading to less-than-ideal sound quality.
