(The canonical location of this blog post is now Sound meter on my web site.)

I am just tinkering; these are estimates:

My laptop's fan is indistinguishable from background noise at a distance of 1 meter, though I can still hear it plenty. This background sound measurement is 18 decibels dBA. (Likely that's the minimum reading on this meter. It's spec'ed for 40-130dB though it works well down to 20 for comparisons.)

My fan is 35 dBA at 1m. It's a household fan about the size of my head.

Music played by my laptop speakers [testing song: "They'll Need a Crane" by They Might Be Giants] is 35-40 dBA at 1m when playing it the loudest I'd want to play it while standing in front of the computer, and 60 dBA at 1m when playing it at near max volume (which fills the room with sound).

One bathroom has a fan which fills the bathroom with 50-60 dBA, and a shower which makes noise at 70 dBA at 1m.
