Hate to break the news, but you have to train the dogs to respond to the noise. You might get their attention briefly, but eventually they'll realize it's not important. Fortunately, my Labrador isn't a huge barker, but all they really need is for you to come and tell them everything is okay. You don't want them to get too excited, so do join in, by barking loudly yourself, "SHUT THE F--- UP!". They like to be useful, and need a job. It's good to alert you sometimes, but they also know it's not a good idea to draw attention to themselves. Just depends how you train them. Some people, yell, throw things, beat, kick, and other nasty things, and the dog figures he's not doing his job well, so he barks more, and louder, until he's afraid to do anything, starts biting people out of frustration.
I keep my dog in the house with me, and if he's in the front of the house, I'll call him. If he stays and keeps barking, I'll go see what's up, tell him he's a good dog, and that's about the end of it. If there's a cat in the back yard, I open the door for him...
The bark control collars are sadistic, they shock the dog, with every loud noise. Had a neighbor that thought they were great, kept trying to talk me into getting one for my last dog, fortunately his neck was unusually large, Rottweiler-Curr mix. Really felt bad for his poor beagle, everytime one of those thump-thump bass boom cars drove past...
