You said the kids weren't talking very loudly----sometimes, "quiet" noises can drive me just as crazy----or, can be even MORE disturbing, to me, than loud noises. Where I live, I can hear people talking, down, on the street (I live in an apartment {flat}), and it's like someone whispering in a movie house (theatre)----and, it drives me NUTS!! Sometimes a loud noise, I can tune-out, more easily----I don't know why.....
