- CIRCUIT DESIGN
AND CAPABILITIES
-
- The technical
choices in current hearing aids allow the consumer a variety
of options.
-
- There are approximately
600 models of circuit designs with digital programming and digital
processing capabilities, in addition to many non-digital circuit
designs. These circuit choices can be categorized into seven
technologies.
-
- LINEAR
- These make all
sounds louder.
-
- TRADITIONAL
COMPRESSION
- These soften
some loud sounds when they occur.
-
- ADVANCED
COMPRESSION
- There are many
special circuits to make hearing aids more comfortable. Your
specialist will guide you.
-
- ADVANCED
DESIGN NON-DIGITAL
- These are unique,
newer, more complex circuits that may be "automatic"
(i.e. no volume wheel necessary).
-
- DIGITAL PROGRAMMABLE
- These higher
technology circuits have 1-13 adjustable bands of compression.
Often they are automatic and use computers to program different
listening environments. Some models use remote controls to provide
more direct client control.
-
- 100% DIGITAL
SIGNAL PROCESSING (DSP)
- Audio sounds
are digitized and then processed. These types of hearing aids
use computers for the fitting process. They contain computer
chips within the hearing aid for further processing.
-
- DEEP CANAL
- For maximum
benefit this circuit depends upon the placement of the hearing
aid near the eardrum, which changes the performance of this type
of hearing aid.
