Listen to a jackhammer
How loud is a jackhammer?
A jackhammer is about 110 dB, with a typical range of 100–130 dB. At the operator's position.
That is about 32 times as loud to the ear as normal conversation and 1e+05 times the sound energy.
Can it damage your hearing?
Yes, with enough exposure. At 110 dBA, NIOSH recommends a daily limit of 1.5 minutes; at the top of the range (130 dB) it is less than a second. Wear earplugs or earmuffs, keep your distance and limit time near the source.
How sound level changes with distance
Decibel figures always depend on distance. For a small source in open air, every doubling of distance lowers the level by about 6 dB; indoors, reflections reduce that drop. Use the sound-vs-distance calculator to estimate the level where you are.

Safe listening time
| Level | NIOSH recommended limit | OSHA legal limit (US) |
|---|---|---|
| 104 dBA | 6.0 minutes | 1.1 hours |
| 107 dBA | 3.0 minutes | 45 minutes |

NIOSH: 85 dBA for 8 hours with a 3 dB exchange rate; OSHA: 90 dBA for 8 hours with a 5 dB exchange rate. General information, not medical advice – see a hearing professional about ringing ears, muffled hearing or pain.

Frequently asked questions
How many decibels is a jackhammer?
About 110 dB, with a typical range of 100–130 dB.
Is a jackhammer louder than a jet engine?
No – a jet engine at takeoff is about 140 dB at 30 m, while a jackhammer is about 110 dB.
How are these levels measured?
With a sound level meter, usually A-weighted (dBA) to match human hearing. Published figures depend on distance and conditions, so treat them as typical values.
