i go through the exact same thing you have described. and like you, i tolerate it and try to be understanding to it during the day even though it is still annoying then. but it is also done late at night - after i am already laying in bed (which faces their backyard). they also have family gatherings - including karaoke - that have gone on after midnight on sunday nights. i hate to be that neighbor that calls the police, but my gosh, i have to go to work!!
