You should be fine dude. I live in a neighborhood and Sunny rarely makes too much noise. The occasional Quack Quack is all. Keep in mind mallards can fly pretty well, so you would have to clip their wings often. They aren't the largest breed either, what do you want in a duck? I can reccomend a breed for you.

Oh and also, if you get only one duck. Be very sure you have plenty of time to spend with it. Ducks believe it or not can suffer emotionally and are flock animals by nature. So if unless you can spend more than an hour a day with it, then get two. I'm homeschooled, so time isn't too much of a problem for me.
