Forty-three of 50 subjects (86%) preferred HiRes 120
over HiRes. Subjects rated strength of preference for
the two strategies on a scale from 1 (weak preference)
to 10 (strong preference). The mean strength of prefer-
ence for the 43 subjects who preferred HiRes 120 was
7.9 (range: 1-10). The strength of preference was rated
as 8 or higher by 26 of the 43 subjects, and 16 of the
43 subjects rated their preference as 10 (strong prefer-
ence). For the 7 subjects who preferred HiRes, the mean
strength of preference was 4.4 (range: 1-9).
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).
