Hah, yes you could pulse microwaves into the room and sense how many sources of screaming there are!
Yes it has to be microwaves, I actually want to use a microwave oven as the transmitter... Then a simple scream detector... a genius idea..:D

Just kidding.

But something in signal strength should change because GHz waves ARE being absorbed by humans, but I was more thinking of a few mW like WLAN. ;)
