WHY
is there high-pitched tinnitus? - Damage
or decay in the hearing system means there is a deficiency in the full range of
audio frequencies delivered to the brain. Usually, it's the uppermost frequencies
that get lost.
- When
tinnitus is present, it can be treated as a noise signal that is standing in for
this deficiency or 'lack'.
WHAT
does Detinnitising do? - The
deficiency can be addressed by filling it with a sound signal requiring more internal
processing resources than the tinnitus. It's the structure of this signal
that's important, not its volume. So it can remain quiet, in the background.
- The perception
of hearing involves the processing of content at successively more advanced levels.
The more of these levels that can be engaged at the same time, the greater will
be the resulting tinnitus suppression.
HOW
does Detinnitising achieve this? - To
most effectively soak up the processing capacity of the hearing system, a Detinnitising
audio signal should include the following characteristics:
- It
should be restricted in bandwidth to match the tinnitus.
- It
should be based on a discontinuous (rather than an unchanging) stimulus.
- It should
include information-bearing sound content.
The
Detinnitising CDs keep the lower processing levels in the auditory system
occupied.
The Detinnitising Amplifier intensifies the action of
the CDs and also keeps the higher processing levels occupied.
