Decibel Sound Meter

How loud is snoring? Measure a night's sleep in decibels

Start a recording before you sleep and stop it in the morning: AVG is the whole night's energy-average level (LAeq), MAX is the loudest single moment, and neither one saves any sound, only numbers.

Record a night to see how loud the snoring really is

A single loud snort can make a night sound far worse than it was — the average usually tells a calmer story. What matters over a night is both how loud the loudest moments are and how much of it is actually noisy. Decibel Sound Meter's Meter tab can run for hours: Start Recording keeps MIN, AVG and MAX running the whole time, the screen stays awake and the recording keeps going if the app is in the background.

Set it up before you sleep

  1. Open the Meter tab and let the live reading settle for a few seconds.
  2. Put the phone on the nightstand, close enough to hear the bed clearly, microphone uncovered (not under a pillow, blanket or phone case flap).
  3. Plug the phone in: a full night of recording and an active microphone use real battery.
  4. Tap Start Recording right before you turn the light off.
  5. In the morning tap Stop Recording; since the session is well over 10 seconds you'll see Stop Recording? — choose Stop & Save (or Stop & Discard to throw it away).

The session lands in History. Open it for Measurement Details: Minimum, Average, Maximum, the Sound Level Over Time chart, and Noise Level Context, which names the closest everyday sound to the night's average.

What the numbers actually mean

AVG is not a simple mean of every sample; it is an energy average (LAeq), so the loud snoring minutes count for much more than their share of the clock. Two nights with very different snoring add up to very different averages:

Two example nights (LAeq, the app's AVG formula)
NightQuiet breathingSnoring burstsAVG (LAeq)Meter word
Light snorer7 h 40 min at 38 dB20 min at 64 dB50 dBModerate
Heavy snorer6 h 30 min at 40 dB1 h 30 min at 78 dB71 dBNoisy

50 dB matches the app's own Moderate Rainfall reference (50 dB) almost exactly; 71 dB sits close to Vacuum Cleaner (70 dB). MAX, on the other hand, captures the single loudest instant (the app holds a Peak value for 2 seconds), which during a real snoring burst is usually higher than either of these averages — that single number tells you how loud the worst snort was, not how the whole night felt.

Questions and answers

Does the overnight recording save the sound of my snoring?
No. The meter analyses the audio in memory to produce the dB numbers and never saves it; only the separate Video tab records actual audio and video, and only when you use it.
Will an all-night recording drain my battery?
Yes, noticeably: the microphone stays active and the screen stays awake for the whole session. Plug the phone in charging overnight if you plan to record until morning.
Does covering the phone with a blanket change the reading?
Yes, muffling the microphone lowers every reading, including the snoring bursts. Leave the microphone uncovered and the phone out in the open on the nightstand for a reading that reflects the room.
How many nights can I keep?
History keeps your last 100 recordings of any kind (oldest deleted first), so you can keep and compare several nights before they roll off.
