dBA

Nope, that does not stand for "doing business as" (although it could), in this case its the noise level rating of your machine.

I'm interested in knowing what the manufacturer's claim as the in the in-cab (enclosed cab) dBA rating is of their products.

I've found one manufacturer that says their acoustical package drops the noise level down to 82-84 (model dependent) at the operator's ear. OSHA indicates that you can expose your ears to 85 maximum for 8 hours. 90 rating limits you to 4 hours.

Anyone else got information that the manufacturer publishes?

Better yet, anyone actually measured it with a sound meter..?

I was thinking of taking mine by the stereo shop and borrowing their spl meter.

It would be nice to have that kind of info.

If in doubt or your getting a head ache etc wear ear protection. I had my hearing tested a few years go now and I was surprised I had problems.

From a lawn mower to excavator I wear ear muffs I can't wear plugs they bother my ears.

I was thinking it might help me to find the right bluetooth ear thingee. Unfortunately, the manufacturers don't really rate them for a specific spl of background noise; they all just claim they work great in "noisy areas" which mostly means a restaurant. You would think somebody would cater to equipment operators' and truck drivers' specific needs.

Company policy at the last outfit I worked for was earplugs 100% of the time on the equipment. I was told you'd get a couple warnings without them, after that they really crack down. The seatbelt rule was the same, except no warnings, just 2 paychecks. :laugh:

I've also read in the brochures about stated dBA ratings in the cab, let's remember that's with the doors closed if a cab is standard equipment. Sometimes I wonder if more couldn't be done to deaden the sound in the cabs, going by the dBA ratings it's shockingly loud.

the Tl140 is rated at 107 Sound Power level(Lwa) and 92 Sound pressure level(Lpa).

Thats Factory specs.Never measured it.

What are those acronyms? Lwa / Lpa

[AWJ Services]

They where in the manual so I included them.Here is something I found that might help explain it?
