I Would say what others here are saying talk to the neigbours, it can't hurt right?
I would also recommend talking to the dogs get to know them, then when they get to know your voice they may quite some.
I too bring in My beagle when he starts up in the yard, I know that I would not like to hear loud beagles bay and barking none stop
it sounds to me like they are the type of parents that want the kids out of their hair and let them run wild and don't attend to them, they even may have a deaf ear to it cause they drown them out, BUT IN THIS CASE we are talking about dogs *same type of thing* if this makes any scense.
Remember it's not the dogs fault remind yourself of this and I truely hope it works out,
