How hearing aids work
The new hearing aids on the market go past the typical aspect of amplification and instead automatically adapt to the circumstances and situations the wearer face. They can pinpoint sounds coming from one specific direction or of a particular type, all the while cutting out unnecessary noise or compressing certain frequencies to make them audible again.
Different Type of Hearing Aids
In BTE hearing aids, all of the technology is contained inside a durable case that sits on the back of the outer ear. Sounds are transmitted to the user’s ear directly, via a small tube or through an ear mold that sits in the ear. BTE hearing aids typically are the largest and most visible, but also the most powerful hearing aids available.
RIC hearing aids rest on the back of the outer ear, just like behind-the-ear hearing aids. The difference between the two however is that the speaker is not inside the case with the rest of the technology. Instead the speaker is inside an ear mold or dome that sits inside the ear and then connected to the case by a wire. Due to this different setup, this type of hearing aid has traditionally been smaller, lighter and more discreet than a BTE, but not powerful enough for wearers with more extensive hearing loss.
ITE hearing aids sit inside your ear. There are various types in this category, from the slightly larger but more powerful ITC (In-The-Canal) to the smaller CIC (Completely-In-Canal) or the virtually invisible IIC (Invisible-In-Canal) Hearing aids.
