In terms of sound transmission and getting down to an NC rating of about 20 in a dedicated home theatre, the door/s are the weakest part of the room. A standard 36mm solid core door with seals has an STC of approximately 30. When you put an STC 30 door on a 10m2 (~100 square feet) wall with an STC of 55, the overall STC of the wall+door is reduced to 36.

So if one is spending the time and money to properly decouple the walls of their dedicated home theatre (or other such quiet space) a door like this is a 'sound' investment.
