Also the sound is right next to the shooters ear.
yes that's about right, dba rating@10m although i thought it was more like 8m but i'm unable to find their testing methodology, and if I'm correct its not at full throttle or under load.
A 3120 is a big saw and its frequencies are different to a 066sthill or 395Huski
I'd much prefer to be on a 3120 all day than a 395
just looked at a 395's dba levels:
Sound pressure level at operators ear 102 dB(A)
Sound power level, guaranteed (LWA) 115 dB(A)
similar but it's a pity sound frequency isn't shown, but i'd bet they are vastly different
BTW the 441 is rated 104 dB and the 880 is rated @ 105 dB at operator ear. Even though my milling 880 has a muffler mod the fact that the exhaust is directed down and away from the operator makes it quieter than my mates 3120.
when doing our OHS retraining every year our trainer would bring out a dba meter and we measured over 120dba for a 395huski and over 130dba for a wood chipper, but i don't have any supporting documentation of that, merely 15 years of experience@5 days a week
