Types
There are basically two
models of hearing instruments available: in-the-ear (ITE) and
behind-the-ear (BTE) instruments.
ITE
In-the-ear instruments include a microphone, a receiver, and
an amplifier in a housing that is worn inside the ear. The
housing also serves as the otoplastic. To obtain a perfect
fit, our in-the-ear instruments are manufactured using the
latest laser technology. The individual ear impression is
scanned via a laser, and the housing is modelled exactly
according to the scan template.
ITE instruments are
available in different sizes and shapes. The size of the
instrument depends on the performance and functions
required:
| CIC: |
"Completely in the canal" - the
smallest of all hearing instruments, these hide
completely in your ear and are virtually invisible when
worn. |
| CS (Mini
canal): |
Almost as small as a CIC but may
feature selected control functions, e.g. program switch
or volume control. |
| CT
(Canal): |
When a smaller model is not
recommended for everyday use. |
| IT (Concha): |
This model enables integration of the
full range of supplemental functions available, e.g.
telecoil or directional microphone. |
Advantages of ITE
instruments
- Inconspicuous and comfortable:
virtually invisible, ideal for sport activities and work.
- Cost-effective: lower battery
power required as the loudspeaker is closer to the eardrum.
- Natural spatial hearing: direct
sound reception inside the ear.
BTE
Behind-the-ear instruments include a microphone, a receiver, and an
amplifier in a housing that is worn behind the ear. Sound
travels from the receiver via the ear hook (soft plastic tubing)
and the ear mould, into the ear canal. BTE instruments are
available in three sizes Mini, Power, and SuperPower, and a wide
range of colours. Colourful hearing instruments or the mouse
design are especially suited to children. The ear adapter can be
coloured or adorned with jewellery items.
Advantages of BTE instruments
- Versatile: numerous application areas, from mild
to profound hearing loss.
- Easy to operate: batteries are easy to replace,
trouble-free on/off switch, simple to put on/remove
- Comfortable: no "plugged" feeling inside the ear.
