This style places the hearing aid behind the ear with a connected tube and mould placed into the ear. The popularity of this style has increased with the evolution in design to what’s known as an open fit, receiver-in-the-canal (RIC) hearing aid. This design connects the hearing instrument into the ear via a slim tube with the hearing aid itself located completely behind the ear minimising visibility. Not only is this solution aesthetically pleasing, and very comfortable to wear, but also provides a naturally sounding listening experience, due to the fact that low-frequency signals are allowed to freely pass back out of the ear canal. Although this solution isn’t suitable for every type of hearing loss it is appropriate for most hearing aid users.
