Wow! Its great to read of so many people wearing hearing protection; I thought I was the exception. Like earlier posters, I keep several pairs of the yellow E.A.R foam cylinders in most of my work jackets, toolboxes, and scattered around the shop. If I'm doing something particularly noisy, I will sometimes throw on a pair of Peltor P9's AND foam plugs. The plugs have a NRR of 22, which I figure cuts the top 22 dB off the long term ambient noise. I have also found them useful in Hotels and for travelling, where peace and quite can get you a good nights sleep. I find that I can re-use the foam plugs (throwing them in a mesh bag and into the washing machine when they get really grimy!) As for hearing the machinery, yes its important, but I find that I can still hear through the plugs. On the flip side, studies have shown constant loud noise is fatiguing. And to that end, I'm more relaxed (but still alert) when I don't have the 110 dB Husqvarna whailing in my ear! Interesting thread. My $0.02.
