How loud is a circular saw?
A circular saw measures 96–107 dB, roughly as loud as a sporting event. At 107 dB it is at or above the 85 dB line where hearing damage starts: NIOSH puts the safe limit at about 3 minutes a day. Normal conversation runs about 60 dB for comparison.

How a circular saw compares
On the decibel scale, 96–107 dB sits above the 85 dB line where sustained exposure damages hearing. Sounds at a similar level:
- Sporting event 94–110 dB
- Car horn at 5 m 100 dB
- Approaching subway train 100 dB
- Jackhammer 100 dB

Is a circular saw dangerous to hearing?
Yes — at 107 dB, a circular saw is loud enough to damage hearing over time. NIOSH limits safe exposure to about 3 minutes a day; use hearing protection beyond that.
