It pays to check: I looked at a Briggs and Stratton 7KW unit that runs
on propane, and was astonished to see a noise rating of 72 db. The unit
is completely enclosed, and is intended for permanent installation, so
it boggles my mind that anyone would buy one unless they intend to have
a sound-dampening enclosure built around it after the installation.

Yuppers, remember when I said build a fake BBQ unit to enclose things?

Again, the Honda EX4500S I have is rated at less than 52 dB. That's
moderately quiet and I find it easy to ignore.

Roughly, the Empire 12 KW genset with the Wisconsin VF4D engine was
not much noisier with an automotive muffler attached to it.
