Measure Description: The Snoring Severity Scale (SSS) is a 9-point, validated scale to measure the severity of snoring. A total of three questions are asked: 1) "How often do you snore, 2) "How long do you snore", and 3) How audible is your snoring. Answers for each of these questions are summed for a total SSS score. A score of '0' would indicate no snoring at all, while a score of '9' would indicate the most severe snoring as measured by the SSS.

Measure Description: A visual-analogue scale (VAS) was used to measure how frequently the subject snored. A score of '0' would indicate the subject never snored, while a score of '10' would indicate the subject snores every single night.
1.Primary Outcome
Title Snoring Severity Scale
Hide Description

The Snoring Severity Scale (SSS) is a 9-point, validated scale to measure the severity of snoring. A total of three questions are asked: 1) "How often do you snore, 2) "How long do you snore", and 3) How audible is your snoring. Answers for each of these questions are summed for a total SSS score. A score of '0' would indicate no snoring at all, while a score of '9' would indicate the most severe snoring as measured by the SSS.

Outcome measure reported as change with use of the device over pre-trial. In this case, a negative ('-') would represent improvement in snoring symptoms, while a positive ('+') number would indicate an increase in snoring severity.

2.Primary Outcome
Title Visual-Analogue Scale, Self-Reported Snoring Habits
Hide Description Quantitative assessment on 1-10 scale. Outcome measurement reported as a percentage change from pre-trial with use of the device. A negative ('-') percentage would indicate a reduction in snoring symptoms as measured by the VAS, while a positive percentage ('+') result would indicate an increase in the measured symptom.
