You know what I think? I think its chipper envy that has Dans panties in a twist. Hey big guy, I got 140hp and a 17" intake parked in MY driveway.
Yes, chipper envy, ya pegged me.
Frig now I have chipper envy too you bastard.

Try inverting the formula for calculating db at range. Each doubling of distance roughly reduces noise levels by 6db. So halving it should add 6 db.... I think. So if a 1590 is roughly 85db at 50 feet according to the EPA, then it should be roughly 91db at 25 feet, 97db at 12 feet, 103db at 6 feet and 109db at 3 feet. So operators should experience noise in the range of 97to 109 db on that math.

Koa said buy a decibel meter, Dan said do your own damm assignment, (I think )
I'm guessing you are young. the answers are easy, with a little work performed besides typing. arborist 101 still requires more effort than asking silly questions. this being IMHO.
I have 4 teenagers, amazing what kids expect others to do.
check out Plas, he wrote the book, and actually has learned his $hit.
Jeez, Plas, dan has you measuring his stuff?
don't do EVERYTHING he says!
I beleive it is 10db that creates an apparent doubling of loudness.
I've got a db meeter from the seventies that I used to set up equalizers using pink noise bands on a vinyl record. It took into account riaa...room effect and speakers! It took a long time to set up a system and I moved to a real time analyzer in the early eighties.
Yea, it's a logarithmic scale, not linear.
The Fletcher–Munson curve also affects perceived loudness.
I would think the the loudest noise would be when the material is cut and thrown agaisnt the metal inside. Sounds like the loudest on my chipper but I don't know.
So EdenT, you an OSHA rep?

I am a firm believer of safety in the workplace but I am more in line with your own common sense approach. I don't need to know how many dB, just that it's loud and me and my crew will suffer injury if we don't wear PPE.
