Worst part about UPS that i didn't know was:
The constant humming (no fan, just electrical) so cant sleep in same room
The loud can't turn it off beeps when power is out.
And none of those come in the product description.

Now imagine the sound at the APC factory, when the power goes out and thousands of UPSes on the charging racks start beeping in sync...! (this is not a hypothetical)
It's enough of a pain to do that rather than configure all 3 UPS devices in my house, I've only ever gotten around to doing it on one.
Can't say I've noticed the electrical hum, except during a blackout. But I don't have mine in a bedroom.
That depends on the UPS, it seems.
I have a pair of Back-UPS 1500s with the external battery packs. They have a button on the front-panel for disabling/enabling the audible alarm (just hold it down for 2s, IIRC).
I personally like the white noise from electronics, so I can't help you there.
