Behind the ear (BTE):
This type of hearing aid sit behind the ear and attach to an earmold which fit in the ear. The older BTE style instruments used a thicker tube which was somewhat visible. The newer style BTE use either a “thin tube” or receiver-in-the-canal technology which are practically invisible when worn. BTEs can be worn by anyone with any type of loss from very mild to very profound.
This hearing aid style fills the entire ear and will accommodate users with a loss from mild to severe.
This style of hearing aid fill up the lower portion of the ear canal. ITCs can fit a mild to moderate hearing loss.
The hearing aid style fits completely in the canal. While less visible when worn, the style has several disadvantages (only fits to a mild hearing loss) and doesn’t allow for volumne control or multiple microphones which thereby limit the instruments ability to perform noise reduction and directionallity. Additionally the battery size is limited by the size of the instrument.
