Sentences in Quiet at 65 dBA
Across all subjects, similar sentence recognition scores in quiet were observed between AutoSense OS
and the AutoSense OS Off program. See the table below.

Sentences in Noise at 65 dBA, + 5 dB SNR Multi-Talker Babble
Across all subjects, better sentence recognition scores in noise were observed when using AutoSense OS
as compared to the AutoSense OS Off program. See table below.

In quiet, 100% of subjects’ AutoSense OS scores were within 10% of their AutoSense OS Off scores and
in noise 90% of subjects’ AutoSense OS scores were better than their AutoSense OS Off scores by 10% or
more. These observed trends further demonstrate that automatic activation of the AutoSense OS
features does not negatively impact sentence recognition in quiet or noise conditions. Additionally, the
improvement in sentence recognition in multi-talker babble noise with AutoSense OS is evident.
Follow-Up Self-Assessment Questionnaire Results
Results were similar across sound quality and listening comfort ratings. All 10 subjects (100.0%) reported
acceptable sound quality in quiet, with 9 subjects (90.0%) reporting strong agreement and 1 subject
(10.0%) reporting slight agreement. Nine subjects (90.0%) reported acceptable sound quality in noise (5
subjects reported “Strongly Agree,” 4 subjects reported “Slightly Agree”), with 1 subject reporting slight
disagreement. All 10 subjects (100.0%) strongly agreed that listening in quiet was comfortable. Nine
subjects (90.0%) agreed that listening in noise was comfortable (7 subjects reported “Strongly Agree,” 2
subjects reported “Slightly Agree”), with 1 subject reporting slight disagreement.
All 10 subjects (100.0%) reported that AutoSense OS on the sound processor was acceptable for use and
daily wear, with 8 subjects (80.0%) reporting strong agreement and 2 subjects (20.0%) reporting slight
agreement with the statements “The sound processor is acceptable for use” and “The sound processor
is acceptable for daily wear”. The majority of subjects (80.0%) also agreed that AutoSense OS on the
sound processor met their listening needs. The 2 subjects that slightly disagreed reported challenges in
