How loud is a generator?

A generator measures 79–97 dB, roughly as loud as a movie theater. At 97 dB it is at or above the 85 dB line where hearing damage starts: NIOSH puts the safe limit at about 30 minutes a day. Normal conversation runs about 60 dB for comparison.

Is a generator dangerous to hearing?

Yes — at 97 dB, a generator is loud enough to damage hearing over time. NIOSH limits safe exposure to about 30 minutes a day; use hearing protection beyond that.
