Decibel Comparison Chart
Use this decibel comparison chart to understand how loud a sound level is in real life. Enter a dB value or choose a common example to compare quiet rooms, traffic, vacuum cleaners, concerts, sirens, and hearing-risk ranges.
Common decibel levels
Decibels are logarithmic, so a small number increase can mean a much larger jump in sound energy. For exposure planning, pair this chart with the noise exposure calculator.
Frequently asked questions
What is a decibel comparison chart?
A decibel comparison chart maps dB levels to familiar sounds so you can understand whether a number is quiet, moderate, loud, or potentially risky for hearing.
How loud is 85 dB?
85 dB is often compared with busy traffic, a loud restaurant, or some power tools. Long exposure at or above this range can increase hearing-risk guidance concerns.
How loud is 100 dB?
100 dB is commonly compared with concerts, clubs, motorcycles, or very loud headphones. Safe exposure time drops quickly as dB rises.
Is a phone decibel reading accurate?
Phone and browser readings are useful estimates, but they are not calibrated like professional sound level meters. Use certified equipment for workplace or legal measurements.
How do I measure decibels around me?
Use a sound level meter or the Measure Decibels iPhone app, then compare the reading with this chart and the noise exposure calculator.
