Advanced
Technology Hearing Aids:
Advanced
Technology Hearing Aid circuitries employ a more recent scientific
development in amplification electronics known as non-linear or
compression amplification. The result is a hearing aid with the ability
to limit the level of incoming sound volume. This delivers a more natural
loudness throughout the patient's entire listening range, without getting
too loud or too quiet as can be the case with conventional hearing aids.
Amplifiers used in advanced technology hearing aids are predominantly from
the Class ‘D’ family with the benefit of longer battery and lower
distortion.
Circuit designs used in this category are composed of either:
-
K-
Amp or Killion Amplifier (Treble Increases at Low Levels) circuitry.
-
Automatic Signal Processing (Base Increases at Low Levels)
circuitry.
-
Automatic Signal
Processing/Automatic Gain Control Input.
-
Automatic Signal Processing/ Automatic Gain Control Output.
Advanced
technology hearing aids can
also employ multi-channel technology, multiple/directional microphone
technology, plus Adaptive Compression and variable release compression.

User
Group:
-
Patients
with mild to moderately severe hearing loss and a reduced tolerance to
loud sounds.
-
Especially
useful for patients with high frequency losses.
-
New
users as well as experienced users.
User
Benefits:
-
Sounds
are balanced; for many users it is neither too weak or too loud, but
provides improved listening comfort in most listening situations.
-
Sounds
are more natural and offer a larger listening range than conventional
electronic hearing aids.
-
Increased
headroom, which translates to less distortion (headroom refers to the
saturation level minus the hearing aid gain and peak input level).
-
Available
in all shell styles. The larger the instrument, a greater range of
controls, features and options can be incorporated and a greater level of
hearing loss can be covered.
Advanced Pricing:
-
Advanced Hearing Aids will cost between
660.00 for the lowest quality products with limited features and
response choices.
-
Top end Advanced products in the Completely
In the Canal size can cost as much as $2395.00.
-
Pricing for any level hearing aid will
depend on four factors.
