The ACS Sound
Processor technology represents acoustic information
in a way that preserves much more sound complexity
than current implant systems. These digital
signal processing (DSP) techniques dramatically
improve the quality of sound data delivered to
multiple electrodes located in the cochlea. For
example, the ACS sound representation strategy
enables the identification and removal of nonspeech
related sounds from noisy environments. In
addition, these processing techniques combined with
our high-density electrode array enables the precise
stimulation of nerves by actually steering the
stimulation field towards the appropriate
neurons. Finally, the precise timing of sound
occurrences will, for the first time, allow users
with bilateral implants to localize sound
direction.
