Behind-the-ear (BTE) hearing aids
Behind-the-ear
(BTE) hearing aids fit comfortably behind-the-ear and are attached
to a soft custom earmold. With BTE hearing aids, the electronics are housed
in a case that fits behind the ear. Sound is directed from the
hearing aid, through the tubing, and through the earmold to the eardrum.
These hearing aids can be modified with connections to external sound
sources such as auditory training equipment, infrared listening systems
or television.
BTE hearing aids can provide more amplification than smaller
devices due to the stronger amplifier and the larger battery.
This style is available in the programmable, digital, and conventional
circuits, and in several colors for hair and skin tone matching.
Advantages

losses.

are suitable for all ages.

most amplification.

aids can be cosmetically appealing with placement behind the
ear.

to handle than the batteries for smaller hearing aids.
