ClearVoice
A clinical study was conducted in 46 adults who had at
least six months experience with HiRes 120 sound pro-
cessing and at least moderate speech perception abili-
ties to investigate the benefits of ClearVoice. ClearVoice
has three adaptive gain settings that allow individuals to
select the setting that provides the best hearing—Low,
Medium, and High. A two-week randomized, crossover
design was used to evaluate ClearVoice-Medium and
ClearVoice-High. ClearVoice-Low was evaluated acutely
during an initial test session. Speech benefit was com-
pared for ClearVoice vs. HiRes 120 without ClearVoice
(Control) using the AzBio sentence test.
Speech understanding in speech-spectrum noise
was significantly better with ClearVoice-Medium and
ClearVoice-High compared to the Control (p < .0001).
ClearVoice-Medium significantly improved speech
understanding in multi-talker babble (p< .02). Speech
understanding was no worse than the Control when
listening in quiet for both ClearVoice-Medium and
ClearVoice-High (p < .0001). Speech understanding
with ClearVoice-Low was no worse than the Control
in quiet, in speech-spectrum noise, and in multi-talker
babble (p <.001).
