CORRECTION - RITE means RECEIVER-IN-THE-EAR
RITE means Right In The Ear and it refers to a very small speaker (referred to in hearing-aid language as the RECEIVER). There is a tiny, thin wire which runs out of the ear canal, in the fold of the ear (barely noticeable) and to the aid which sits behind the ear (BTE).
This is the system I am using. My low hearing is perfect, then it gets worse as it goes up in frequency. I have open domes on left and right which allow low sounds to go by the tiny speaker while the mid, upper-mid and high frequences are picked up by the mics in the BTE aid and are amplified into the ear canal.
