Another possible source of unexpected extremely loud noises: cleaning things with compressed air. If you blow it through a small orifice of the right dimensions then it can act as a whistle. The energy will be concentrated at one frequency, and compressed air generally blows a lot harder than lung power.
I first heard of this from a Youtube video, possibly from one of AvE's, although it could have been from somebody else's.

- dvtv75 9y agoI 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.
