Acoustic doors?

How much do you want to spend and how much sound do you want to stop? An opening as small as 1/4" between the two rooms will cause the sound to get through. Are aesthetics important? Most sound is stopped using gasketing that can be either surface mounted (cheaper) or concealed in the door. Phil Brady.

I would suggest solid core door, not a panel door. Prehung on an exterior frame. Order it without the sill and get a surface mount or recessed automatic door bottom. In addition to the weatherstrip installed in the frame get some surface mounted acoustic seals. Hager hinge makes some stuff at hagerhinge.com . Use 747S or 730S for door bottom and 866 for around frame. This stuff will not be available at home center but is readily available from commercial door suppliers. I used to sell this stuff in another life. Phil Brady.
