Decibel Chart: Decibel Levels of Common Sounds

This decibel chart lists 30+ common sounds in decibels: a whisper is about 30 dB, normal conversation 60 dB, city traffic 80–85 dB, and a rock concert 105–110 dB. Hearing damage risk starts at 85 dB for sustained exposure (NIOSH), and sounds at 120 dB or more — sirens, fireworks — can injure hearing immediately.

Barking dogs (kennel, close range) 88.4–100.3 work High — NIOSH kennel measurement over 10 minutes — above the 85 dB line the whole time NIOSH

Tap any sound in the decibel chart for its own page in decibels: how loud it is, how long is safe, and what else hits that level. Every value above is sourced to published figures from the CDC, NIOSH, NIDCD or ASHA — linked per row. None of these numbers are invented. Our own calibrated measurements of real environments will be added and marked “measured by us” once recorded.

What is the decibel scale?

The decibel (dB) scale measures sound pressure level, and it is logarithmic, not linear. 0 dB is the threshold of human hearing, not silence, and the numbers climb slowly while the sound energy climbs fast: a 3 dB rise doubles the energy, and a 10 dB rise sounds to the ear about twice as loud. That is why NIOSH halves the safe exposure time for every 3 dB above 85 dB. This decibel chart — also called a noise level chart, sound level chart or dB chart — places 30+ everyday sounds on that scale, from a 10 dB breath to a 140 dB jet engine.

How loud is a specific decibel level (in decibels)?

Jump to a level to see what it sounds like and how long is safe:

How loud is 70 decibels (70 dB)?

70 dB is about the loudness of a washing machine or dishwasher from a few feet away — clearly audible, slightly effortful to talk over, but not harmful. The decibel scale is logarithmic: 70 dB carries ten times the sound energy of 60 dB (normal conversation), and 80 dB carries one hundred times more.

What decibel level causes hearing damage?

NIOSH’s recommended exposure limit is 85 dB(A) averaged over an 8-hour day. Each 3 dB above that halves the safe duration: 88 dB is safe for about 4 hours, 94 dB for about an hour, 100 dB for about 15 minutes. At 120 dB and above, sound can cause immediate injury. See safe decibel levels for the full safe-versus-risk breakdown by level. If you are worried past exposure has already taken a toll, the free hearing age test gives a quick read on your high-frequency hearing in about a minute. The WHO additionally recommends keeping average road-traffic noise exposure below 53 dB Lden to avoid broader health effects — see the city sound map for how major cities compare.
