Can wood frame condos be soundproofed?

Question

I live in a woodframe condo and have some problems with the neighbors below me slamming their doors. I have spoken to them, they have improved about as much as can be expected, but it still is annoying. Should I carpet the floor above where their front door is (which is exactly below my front door) or wouldn't it make a difference.

By the way, most of my place is ceramic tile.

Answer 1

buy them some "cushioned" weather stripping for their door...gl
