I bought a compressor a couple of years ago, and good grief is that thing noisy.
I always wearing hearing and eye protection when using it, and I'm glad for it. First time I tested the emergency release valve, I didn't know which direction it would release the air. If I hadn't been wearing safety glasses, I could have lost my eyes as it released directly into my face. I now have a rule of not allowing anybody in the workshop with me while using it, if they're not wearing both hearing and eye protection.
