I can recommend the Acoustic Sciences door seal as one option
http://www.acousticsciences.com/products/door-seal-kit
I had ASC design a sound proof listening room for me and this was part of the setup, albeit installed in dual solid doors (i.e. one door opening one way and another opening the other way). It will certainly keep out sound coming in and your neighbors will only hear you if they stand outside.
Be warned however that as dweller observes none of this will help with bass transmission which will be happening through the floor, walls and even ceiling if you fully energize the room
