Decibel comparisons
How loud is 50, 60, 70, 80, 90 and 100 dB?
Decibel numbers are hard to picture. Here is what each level sounds like in everyday life, where the hearing-risk zones start, and why a few dB make a big difference.
Decibel comparison chart
| dB | Sound | Level | Zone |
|---|---|---|---|
| ~10 | Breathing, rustling leaves | Comfortable | |
| ~30 | Whisper | Comfortable | |
| ~40 | Quiet room, library, fridge hum | Comfortable | |
| ~50 | Light rain, quiet office | Comfortable | |
| ~60 | Normal conversation | Comfortable | |
| ~70 | Vacuum cleaner, busy restaurant | Loud | |
| ~80–85 | Busy city traffic (80–85 dB) | Loud | |
| ~90 | Gas lawn mower | Risky over time | |
| ~95 | Motorbike passing | Risky over time | |
| ~105–110 | Rock concert, nightclub (105–110 dB) | Harmful quickly | |
| ~120 | Emergency siren up close | Painful / danger | |
| ~130 | Jet engine nearby — pain threshold | Painful / danger |
How loud is 50 dB?
Comfortable
Sounds like: Quiet office, light rain, a refrigerator up close.
Calm background. Easy to talk quietly and concentrate.
How loud is 60 dB?
Comfortable
Sounds like: Normal conversation at about 1 m, a busy office, background music.
Comfortable everyday level. No hearing risk on its own.
How loud is 70 dB?
Loud
Sounds like: Vacuum cleaner, busy restaurant, a shower, freeway traffic from the roadside.
Noticeably loud and tiring over long periods; you raise your voice to talk.
How loud is 80 dB?
Loud
Sounds like: Heavy city traffic, a garbage disposal, an alarm clock up close, a food blender.
Loud. Around 80–85 dB is where long daily exposure starts to matter.
How loud is 90 dB?
Risky over time
Sounds like: Gas lawn mower, a motorbike passing, a power drill, a subway train.
NIOSH suggests about 2.5 hours a day at 90 dBA. You need to shout to be heard.
How loud is 100 dB?
Harmful quickly
Sounds like: Hand dryer up close, chainsaw, a loud nightclub, headphones at max volume.
About 15 minutes a day under the NIOSH guideline. Hearing protection advised.
Why the same sound reads differently
Distance changes everything: from a small source, doubling your distance lowers the level by about 6 dB. Rooms with hard surfaces add reflections, and soft furnishings absorb sound. Measurement weighting matters too — safety limits use A-weighted dBA, which plays down low rumble. Our online decibel meter gives an approximate, unweighted reading.

Frequently asked questions
Is 60 dB loud?
No. 60 dB is about the level of a normal conversation at one metre. It is comfortable for most people and is not considered a hearing risk on its own.
Is 70 dB loud?
70 dB is noticeably loud — like a vacuum cleaner or a busy restaurant. It is generally not harmful over a day, but it can be tiring and makes conversation harder.
How loud is 80 dB?
80 dB is like heavy city traffic or a blender. It sounds about twice as loud as 70 dB. Long daily exposure around 80–85 dB is where hearing-safety guidance begins to apply.
Is 90 dB too loud?
90 dB, like a gas lawn mower, is loud enough that NIOSH recommends keeping daily exposure to about 2.5 hours. Hearing protection is a good idea for longer tasks.
How loud is 100 dB?
100 dB is very loud — a chainsaw, nightclub or headphones at maximum. NIOSH guidance suggests no more than about 15 minutes a day at 100 dBA.
Does 10 dB more sound twice as loud?
Roughly, yes. An increase of 10 dB is ten times the sound energy, and most listeners perceive it as about twice as loud. An increase of 3 dB doubles the energy but sounds only slightly louder.
