Receiver-In-The-Canal (RITC) devices are a terrific solution on many
hearing loss cases. However, they have their limitations too. A classic
scenario that pushes it to the limit is if you are using open-fit
device, while having a severe hearing loss.
When you use open-fit, what happens is, that the sounds inside your ear can leak outside easily because the open-fit tip isn’t sealing your ear. If on top of that, you have a severe hearing loss, the sounds in your ear are transmitted louder than on other cases. This combination might cause feedback.
There are few drawbacks to this solution: first, you have to have an ear impression and the earmold is tailor made for you. Second, and earmold isn’t as ventilated as the open-fit tip. It is totally up to you to weigh it against the feedback noises.
