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.
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.

BreathFlow Limitations: While BreathFlow provides valuable insights, it cannot diagnose sleep apnea or other sleep disorders. If BreathFlow detects concerning patterns, use this data as a starting point for discussion with your healthcare provider, who may recommend a formal sleep study.
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:
35.7 Average Baseline Score
+20% Score Increase with Alcohol
28.3 Best Score (No Alcohol + 6h+ Sleep)
12-68 Score Range Observed
12-Week Study Timeline and Observations
Week 1
Baseline Establishment
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.
Week 2
Back2Sleep/Nastent Testing Begins
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.
Week 3
Sleep Duration Impact Discovered
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.
Week 4
Alcohol Effect Confirmed
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.
Weeks 5-12
Long-term Pattern Analysis
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
With Alcohol:
41.7
Without Alcohol:
34.8
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
Less than 6 hours:
41.3
More than 6 hours:
36.3
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 |
Key Finding: Optimal snoring reduction requires BOTH avoiding alcohol AND getting adequate sleep (6+ hours). Either factor alone can increase snoring scores by approximately 47% compared to optimal conditions (41.3/41.7 vs 28.3).
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:
Back2Sleep/Nastent Nasal Stent
Consistently reduced loud snoring episodes. Achieved lowest score of 14. Eliminated "epic" snoring sounds in most recordings. Most effective device tested.
Anti-Snoring Ring (Acupressure)
Mixed results. Highest score of 68 recorded while wearing ring. Inconsistent performance suggests limited effectiveness for this individual.
Tongue Stabilizing Device
Under evaluation at time of study conclusion. Early results suggested moderate effectiveness but discomfort limited compliance.
Future Tests Planned
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.
Why Scores Vary:
- - 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.
Evidence-Based Recommendations for Reducing Your Snore Score
Based on our 12-week study data and clinical research, here are the most effective strategies for reducing your SnoreLab score:
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.
Optimal Strategy: Combining lifestyle changes (no alcohol, adequate sleep) with an effective device like Back2Sleep provided the best results in our study, achieving scores as low as 12-14 compared to baseline averages of 35.7.
When to Seek Medical Evaluation: SnoreLab Limitations
While SnoreLab is an excellent tracking tool, it has important limitations. You should seek medical evaluation if:
Consistently High Scores (50+)
Epic or severe snoring scores that persist despite interventions may indicate obstructive sleep apnea requiring professional assessment.
Daytime Symptoms
Excessive daytime sleepiness, morning headaches, or difficulty concentrating despite adequate sleep time suggest sleep quality issues.
Partner-Witnessed Apneas
If your partner observes you stop breathing during sleep, this is a strong indicator of sleep apnea requiring immediate evaluation.
BreathFlow Alerts
Frequent breathing irregularities detected by SnoreLab's BreathFlow feature warrant discussion with a healthcare provider.
Important Disclaimer: SnoreLab cannot diagnose sleep apnea or other sleep disorders. Only a polysomnography (PSG) sleep study can provide an official diagnosis. Use SnoreLab data as objective information to share with your doctor, not as a replacement for professional medical evaluation.
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
Review audio samples to qualitatively assess snoring changes. Our testing showed Back2Sleep particularly effective at eliminating "epic" snoring sounds.

What is a good SnoreLab score?
SnoreLab scores are categorized as: Quiet (under 10), Light (10-25), Loud (25-50), Epic (50-100), and Severe (100+). A score under 25 is considered normal. The app's average user score is 25. Our 12-week study showed optimal conditions (no alcohol, 6+ hours sleep) achieved scores around 28, while alcohol consumption raised scores to 42+.
How accurate is SnoreLab for measuring snoring?
A 2024 clinical study published in MDPI found SnoreLab achieved 94.7% accuracy in detecting snoring events when compared to polysomnography (PSG), the gold standard sleep study. The app is recognized by medical professionals in Japan and used as reference data at snoring outpatient clinics. However, it cannot diagnose sleep apnea - only a formal sleep study can do that.
Can SnoreLab detect sleep apnea?
SnoreLab cannot diagnose sleep apnea - only a polysomnography (PSG) sleep study can provide an official diagnosis. However, SnoreLab can help identify patterns suggestive of sleep apnea, such as periodic snoring followed by silence (potential apnea events), very high scores consistently above 50, and the BreathFlow feature can detect some breathing irregularities. Use SnoreLab data as a conversation starter with your doctor.
How do I reduce my SnoreLab score?
Based on our 12-week study, the most effective ways to reduce your score are: avoid alcohol before bed (20% score reduction), get 6+ hours of sleep (12% improvement), use an intranasal device like Back2Sleep (eliminated loud snoring in our testing), sleep on your side, and maintain a healthy weight. Combining lifestyle changes with an effective device provided the best results.
What is SnoreLab BreathFlow?
BreathFlow is a premium SnoreLab feature that analyzes your breathing patterns throughout the night beyond just snoring. It detects breathing irregularities, potential pauses, and respiratory effort. BreathFlow uses your phone's microphone to identify breathing sounds and can highlight periods of irregular breathing that may warrant medical attention. It's not a diagnostic tool but provides additional insights for discussions with healthcare providers.
How to use SnoreLab properly?
For best results: 1) Place phone 30-60cm from your head on the nightstand, 2) Keep phone plugged in to prevent battery drain, 3) Disable notifications and enable Do Not Disturb, 4) Record consistently at the same phone position, 5) Log factors like alcohol, medications, devices used, 6) Record for at least 7 nights to establish baseline, 7) Use airplane mode to prevent interruptions while keeping recording active.
What does Epic snoring mean in SnoreLab?
Epic snoring in SnoreLab indicates a score between 50-100, representing significant snoring that may disturb bed partners and potentially indicate underlying sleep issues. Epic scores are characterized by loud, frequent snoring throughout much of the night. Consistently epic scores warrant medical consultation to rule out obstructive sleep apnea (OSA). Our study found epic scores most commonly occurred with alcohol consumption combined with short sleep duration.
