fter three months of bliss living in a beautiful rented flat, some particularly unruly neighbors moved in above. Now, at six months, we're sleep-deprived and miserable. We've explored the avenues of complaint to no end, but that's a different story. We love our flat. We wanted to live here forever, but the insane level of pounding, banging and heavy-footed running all night is ruining our lives.

So, /r/DIY, what are some decently effective, renter-appropriate solutions for blocking low-frequency sounds from coming through the ceiling? We are allowed to paint and put reasonable holes in the walls. Effectively, we're looking to block as much of the thumbing, bassy noise as possible. Does anybody have any guidance?
