Receiver in the Canal:
BTE hearing instruments that place the loudspeaker directly in the ear without a fitted earmold are often referred to as “Receiver in the Canal” instruments. These instruments use soft ear inserts, typically of silicone, to position the loudspeaker in the patient’s ear.
Some of the advantages with this approach include improved sound quality, reduced case size, “open-fit” technology, and immediate patient fitting.
Cross systems are used for people with hearing loss in one ear or significantly more in one ear, this system allows the user to wear technically a microphone in one ear and the speech is transferred into a speaker in the good ear, whilst the cone in the good ear allow normal hearing
BTE Bi Cross System is the same as the Cross system, however it can also enhance the hearing in the individuals better ear by enhancing the volume of the input, therefore channelling the sound into the good ear, whilst enhancing the clarity and volume for it also.
