How Loud Is Snoring? Decibels Explained
Most snoring sits between about 40 and 60 decibels, roughly a quiet office up to normal conversation. Heavy snoring can pass 80 dB, and rare extreme cases top 90 dB. Loudness alone cannot diagnose anything, so see your GP about worrying patterns.
If you have ever wondered how loud is snoring decibels really tell us, the answer is reassuring. Snoring loudness is one of the easiest things to measure and one of the most misunderstood. A loud night does not mean something is wrong, and a quiet night does not mean all is well. Here is what the decibel numbers actually mean and how to read your own.
How loud is snoring in decibels on a normal night?
Studies of real sleepers put typical snoring around 45 to 60 dB at the bedside. One study of 162 people found a median peak of 45.4 dB(A), with a louder group averaging 56.7 dB(A). For comparison, a quiet library is about 40 dB and normal conversation is around 60 dB.
Snoring is graded by loudness like this:
| Band | Decibels | Sounds like |
|---|---|---|
| Mild | 40 to 50 dB | Quiet office or soft speech |
| Moderate | 50 to 60 dB | Normal conversation |
| Loud | over 60 dB | Raised voice, getting toward a busy road |
Heavy snoring has been recorded above 80 dB, and the loudest case on record reached 93 dB, which is close to a lawnmower. Loud snoring is common and usually not serious, but it can disturb a partner well before it reaches those extremes.
How do phone apps measure snoring loudness?
Your phone microphone reads sound pressure and converts it to a decibel estimate, sampling many times a second through the night. An app then flags the stretches that cross a snoring threshold and logs how loud and how frequent they are. This is why two apps can report slightly different numbers: phone position, room layout and how the maker calibrates the microphone all shift the reading.
A few things to know before you trust a single figure:
- Distance matters. A phone on the nightstand reads quieter than one on the pillow.
- Background noise (a fan, traffic, a partner) can inflate the count.
- Trends over many nights tell you far more than any one peak.
Kip records and scores all of this on the iPhone itself, so the audio never leaves your phone. If you want the basics of capturing a clean recording, see how to record snoring on iPhone, and how to track snoring for reading the trend over time.
Does loud snoring mean sleep apnoea?
Louder snoring is statistically linked to more severe obstructive sleep apnoea, but the groups overlap heavily, so loudness on its own cannot confirm or rule it out. A consumer app, including Kip, measures loudness and frequency. It does not measure breathing pauses or blood oxygen, and only a sleep study can diagnose apnoea. The signs worth raising with a GP are gasping or choking, witnessed breathing pauses, and daytime sleepiness, not volume alone. If those ring true, read snoring vs sleep apnoea and then book a GP appointment.

FAQ
Is 60 dB snoring loud?
Around 60 dB is roughly the volume of a normal conversation, so it sits at the loud end of typical snoring. It is enough to disturb a partner in the same bed. Loud snoring is common and usually not caused by anything serious, but it is worth a GP chat if it affects your or your partner’s sleep.
Can a phone really measure snoring decibels accurately?
A phone gives a useful estimate rather than a calibrated reading. Exact numbers shift with microphone quality, distance and room noise. The reliable value is the trend across many nights, which is harder to fake than a single loud peak and shows whether a change has actually helped.
What is the loudest snoring ever recorded?
A Swedish woman with sleep apnoea was recorded at a peak of 93 dB, listed by Guinness World Records in 1993. Some reports cite individual peaks above 100 dB. These are rare extremes, far above the 40 to 60 dB most people produce.
