I'm going to say one week. This is probably way too much time, but I have had a situation or two where I have had some big items that I couldn't deal with by myself, and it takes a little bit of time to make certain arrangements.
If you're comfortable talking to these people in person about the noise, do so now. They might not even be aware that they are causing a problem, in addition to the trash situation. Other options are to make a complaint with the homeowner's association, landlord, or police.
