What is an Invisible Hearing Aid?

 

Amongst the many various styles that are available, one of the most popular in the last few years has been the invisible type. Tiny and discreet, it fits deep within the ear canal enabling it to be virtually undetectable, providing the wearer with added personal confidence. An invisible hearing aid can be worn to combat any level of hearing loss but does it perform as efficiently as a more conventional model?

Style and Design

These small, Completely in Canal (CIC) hearing aids are indeed invisible. Some are designed to fit as closely as within a millimetre or two of the ear drum while others aren’t fitted quite so deeply. They are supplied fully customisable but always ensure that your audiologist is qualified in taking the complex impression of your ear canal otherwise your hearing could suffer even more. Such invisible designs are unobtrusive and comfortable to wear. Each one will always have an extraction cord fitted to enable you to remove it easily.

Benefits

One of the main benefits of an invisible CIC style is that where it rests in your ear canal it is in contact with the bonier area which doesn’t resonate in the same way as the exterior part of your ear which largely comprises of cartilage. This avoids the irritating feeling of being able to listen to the sound of your own voice inside your head which is professionally referred to as occlusion. Due to its locality within the ear canal, the invisible hearing aid has its tiny microphone in a position that doesn’t cause any interference when using the telephone. This is a positive advantage for anyone who has a job which involves answering frequent calls. Hearing sounds in your immediate vicinity both in front and behind is known as acoustic localisation. An invisible hearing aid performs extremely well in this area as it doesn’t obstruct the outer ear.

Disadvantages

The miniature size of an invisible hearing aid limits its strength and prevents the inclusion of wireless technology which can provide a superior performance. Deciphering sound in very noisy environments can sometimes be difficult due to there only being enough space for a single microphone rather than a dual version. The unit needs a regular and thorough maintenance regime which includes brushing the surface to keep it free of ear wax. It will usually contain a filter to deter a build up of wax and needs to be changed frequently. Consequently, anyone experiencing a limited level of manual dexterity might find it difficult to maintain an invisible hearing aid. In addition, the shape of your ear canal will ultimately determine the suitability of wearing this type of model. People with ear canals that are much straighter often experience difficulties in keeping them fitted in correctly as even the action of eating will cause them to work their way into the outer ear.
