How loud is a jackhammer?
A jackhammer measures about 100 dB, roughly as loud as a car horn at 5 m. At 100 dB it is at or above the 85 dB line where hearing damage starts: NIOSH puts the safe limit at about 15 minutes a day. Normal conversation runs about 60 dB for comparison.

How a jackhammer compares
On the decibel scale, 100 dB sits above the 85 dB line where sustained exposure damages hearing. Sounds at a similar level:
- Car horn at 5 m 100 dB
- Approaching subway train 100 dB
- Sporting event 94–110 dB
- Motorcycle 95 dB

Is a jackhammer dangerous to hearing?
Yes — at 100 dB, a jackhammer is loud enough to damage hearing over time. NIOSH limits safe exposure to about 15 minutes a day; use hearing protection beyond that.
