As someone who works in a garage most of the day as a mechanic, just what is office noise? they all seem pretty quiet to me. What are we trying to reduce?
Around the shop I carry a few pairs of disposable foam Howard Leight earplugs. They come in small plastic bags, or you can buy them in boxes of 500. I'll hand them out to apprentices I catch not wearing ear protection or to old timers so they can sneer at me. they work wonders for any kind of noise. We once had a garbage truck plow through a rolling dumpster out back and I never knew about it until lunch.
