Sounds like a perfect use for an Arduino driven speaker.
There are thousands of publicly posted circuits that will probably net a simple solution, or the name of a local person who would love to help/ adapt one for this purpose.

Subject: [RE-wrenches] Off Grid Alarm
We are looking for an audible alarm that will not drive the pets crazy if
it stays on for hours when no one is home. At present, only a red indicator
light goes on when the grid is down.
It would need to run off 120 VAC. Does anyone have any suggestions?
Thanks,
Drake
