As Going Quackers said, the breeding doesn't have anything to do with the noise. Otherwise you could also stereotype humans on that as well too, and that would be a bad thing...
Anyways, I also agree that separating or even giving up the males (that they might have grown and lived with) is very stressful to birds, and might also cause quite the opposite effect of what you're trying to do. Yes, everybody wants to keep the females for the eggs but honestly, if you're wanting some quiet(er) ducks Pekins are definitely the wrong breed to go with. Not saying you should get rid of them or anything like that...
Muscovies would be very quiet, even the females, and they chirp not quack. Yet the disadvantage of those would be having to clip their wings as they can fly very well. My Khaki's are also pretty quiet, calm, good egg layers and smaller in size. Maybe that is another aspect of the annoying complaining neighbors. White just sticks out. Yet, there are simply people that will never be pleased as long as anyone around them is happy and they have to cause trouble or at least trying to get their way... I know, that doesn't help much in the decision making, but just thought I'd mention it
