You can run a fan at night to drown out most kinds of noises. If that doesn’t work, download a white noise generator and set it at “pink” noise (like white noise but more emphasis on lower frequencies) and that will drown out yelling as well as the bass from doors.
If that doesn’t work, then I agree about playing loud music during the day when you aren’t there. If they are up all night, then you can keep them up all day and something has to give. Either they will confront you about it which allows you to make a compromise, or they will get the hint (probably the former if they are white trash). If you’re looking for something to blast then my new poisons are All That Remains and Dark Tranquility.
