What is SnoreLab and How Does It Work?
SnoreLab is a smartphone application that uses your phone's microphone to record, measure, and analyze your snoring throughout the night. The app calculates a Snore Score based on the loudness, duration, and frequency of your snoring, providing an objective measure you can track over time.
Smart Recording
Advanced algorithms filter background noise to isolate snoring sounds. Records only when snoring is detected to save storage and battery.
Snore Score Calculation
Proprietary algorithm weighs loudness (decibels), duration (time spent snoring), and frequency (number of snoring episodes) into a single score.
Factor Tracking
Log factors like alcohol, medications, sleeping position, and remedies to identify correlations with your snoring patterns.
BreathFlow Analysis
Premium feature that analyzes breathing patterns beyond snoring, detecting potential irregularities that may indicate breathing issues.
Understanding Your Snore Score: Complete Interpretation Guide
One of the most common questions SnoreLab users ask is "What is a good Snore Score?" The app uses a proprietary scoring system that categorizes your snoring intensity. Understanding these thresholds helps you set realistic goals and know when to seek medical advice.
How to Use SnoreLab Properly: Step-by-Step Setup Guide
Proper setup is essential for accurate snoring measurements. Phone positioning, environmental factors, and consistent recording habits all affect your results. Follow these steps for reliable data:
Position Your Phone Correctly
Place your phone 30-60cm (1-2 feet) from your head on a nightstand at mattress height. Keep the microphone unobstructed and pointing toward you. Consistent positioning is crucial for comparable results across nights.
Optimize Phone Settings
Enable Do Not Disturb mode, disable notification sounds, and keep the phone plugged in to prevent battery drain. Use airplane mode if needed, but note this won't affect recording. Close other apps to prevent interruptions.
Log Contributing Factors
Before sleep, log relevant factors: alcohol consumption, medications taken, sleeping position, room conditions, any remedies or devices used (like Back2Sleep), and your sleep timing.
Establish Your Baseline
Record for at least 7 consecutive nights before drawing conclusions or testing remedies. This establishes your baseline score accounting for natural night-to-night variation. Our study found scores varied by up to 40 points even under similar conditions.
Track Remedies Systematically
When testing anti-snoring solutions, use the remedy for at least 5-7 nights before evaluating effectiveness. Compare average scores rather than individual nights due to natural variability.

Our 12-Week SnoreLab Study: Real-World Data and Findings
The Japanese Back2Sleep team conducted a comprehensive 12-week observational study using daily SnoreLab recordings to understand how various factors affect snoring scores. Here are our key findings:
12-Week Study Timeline and Observations
Max: 56, Min: 18, Average: 35.7. Initial observations showed periodic snoring increases at night onset. Surprising variability in scores noted even under similar conditions.
Max: 36, Min: 19, Average: 29.6. Days using the intranasal stent showed absence of loud snoring episodes. Clear improvement from baseline week, particularly in eliminating "epic" snoring sounds.
Max: 58, Min: 14, Average: 27.4. Strong correlation between short sleep (under 3 hours) and worst scores discovered. Even with Back2Sleep device, sleep deprivation worsened snoring.
Max: 48, Min: 18, Average: 30.0. Four nights with alcohol consumption showed consistently worse scores (42 average vs 28 without alcohol). Sleep onset snoring particularly severe.
Max: 68, Min: 12, Average: 30.7. Scores stabilized around 30-31 average. The worst score (68) occurred while testing anti-snoring ring without Back2Sleep. Best score (12) achieved with Back2Sleep + no alcohol + 7+ hours sleep.
Analysis 1: Alcohol's Impact on Snoring Scores
Alcohol Impact on Snore Scores
Our data confirmed what sleep medicine research has long established: alcohol significantly worsens snoring. Alcohol relaxes the throat muscles, making them more likely to collapse and vibrate during breathing. Key findings:
- With alcohol: Minimum score 32, Maximum 51, Average 41.7
- Without alcohol: Minimum score 18, Maximum 56, Average 34.8
- Average increase: 20% higher scores with alcohol consumption
Interestingly, while alcohol raised the minimum score significantly (32 vs 18), the maximum score of 56 occurred without alcohol - suggesting other factors can worsen snoring even more dramatically. However, alcohol consistently raised the "floor" of snoring intensity.
Analysis 2: Sleep Duration's Effect on Snore Scores
Sleep Duration Impact on Scores
Shorter sleep duration correlates with worse snoring scores, though the effect is less dramatic than alcohol. This finding has an interesting explanation: snoring tends to be more intense during early sleep stages (particularly during the first sleep cycles). With shorter sleep, a greater proportion of total sleep time is spent in these heavier snoring phases.
Additionally, sleep deprivation leads to deeper sleep (increased slow-wave sleep), which further relaxes throat muscles and increases snoring intensity. This creates a problematic cycle where poor sleep quality from snoring leads to sleep deprivation, which then worsens snoring.
Combined Effect: Alcohol + Sleep Duration Cross-Analysis
| Condition | Average Score | Interpretation |
|---|---|---|
| No Alcohol + 6+ Hours Sleep | 28.3 | Optimal conditions - best achievable score |
| No Alcohol + Less than 6 Hours | 41.3 | Sleep deprivation alone worsens snoring |
| Alcohol + 6+ Hours Sleep | 41.7 | Alcohol negates benefit of adequate sleep |
| Alcohol + Less than 6 Hours | No Data | Combination avoided during study |
Anti-Snoring Device Testing Results
Throughout the 12-week study, we tested multiple anti-snoring devices and tracked their effectiveness using SnoreLab. Here are our findings:
Consistently reduced loud snoring episodes. Achieved lowest score of 14. Eliminated "epic" snoring sounds in most recordings. Most effective device tested.
Mixed results. Highest score of 68 recorded while wearing ring. Inconsistent performance suggests limited effectiveness for this individual.
Under evaluation at time of study conclusion. Early results suggested moderate effectiveness but discomfort limited compliance.
Non-prescription mandibular devices, nasal dilator strips, and combination therapies remain to be tested systematically.
The Back2Sleep intranasal stent demonstrated the most consistent results in our testing. By keeping the nasal airway open, it reduces the air turbulence that causes snoring sounds. The device was particularly effective at eliminating the loud snoring episodes that occur during sleep onset.
Understanding Snore Score Variability
One of the most important findings from our study was the significant night-to-night variability in snoring scores, even under seemingly similar conditions. The scatter plot above shows substantial variation despite clear trends.
- - Phone positioning: Movement during sleep changes the phone's position relative to the sleeper
- - Sleep stages: Different sleep stages have different snoring intensities
- - Daily factors: Stress, fatigue, nasal congestion, and other daily variables
- - Environmental changes: Room humidity, temperature, and ambient noise
- - Sleeping position: Natural position changes throughout the night
This variability is why establishing a baseline over multiple nights and comparing weekly averages (rather than individual nights) is essential for evaluating remedy effectiveness.

Avoid Alcohol Before Bed
Our data showed a 20% average score increase with alcohol. Avoid drinking within 4 hours of bedtime for best results.
Get 6+ Hours of Sleep
Adequate sleep duration correlated with 12% lower scores. Aim for 7-8 hours for optimal sleep architecture.
Use Proven Anti-Snoring Devices
Intranasal devices like Back2Sleep showed the most consistent results in eliminating loud snoring.
Track Progress Consistently
Use SnoreLab to objectively measure intervention effectiveness. Compare weekly averages, not individual nights.
When to Seek Medical Evaluation: SnoreLab Limitations
While SnoreLab is an excellent tracking tool, it has important limitations. You should seek medical evaluation if:
Epic or severe snoring scores that persist despite interventions may indicate obstructive sleep apnea requiring professional assessment.
Excessive daytime sleepiness, morning headaches, or difficulty concentrating despite adequate sleep time suggest sleep quality issues.
If your partner observes you stop breathing during sleep, this is a strong indicator of sleep apnea requiring immediate evaluation.
Frequent breathing irregularities detected by SnoreLab's BreathFlow feature warrant discussion with a healthcare provider.
Tracking Back2Sleep Effectiveness with SnoreLab
SnoreLab is the ideal tool for measuring the effectiveness of anti-snoring devices like Back2Sleep. Here's how to use them together for best results:
Establish Your Baseline
Record 7-10 nights WITHOUT Back2Sleep to establish your baseline snoring score. Log all relevant factors (alcohol, sleep duration, etc.) consistently.
Begin Device Testing
Start using Back2Sleep and mark it as a "remedy" in SnoreLab. Allow 2-3 nights for adjustment before evaluating results.
Track for 7+ Nights
Continue recording for at least 7 nights with the device. Keep other factors as consistent as possible for valid comparison.
Compare Weekly Averages
Use SnoreLab's trend analysis to compare average scores with and without the device. Our study showed Back2Sleep reduced average scores from 35.7 to 29.6.
Listen to Recordings
