I am going to insulate the room for sound (in part so that I can play at night without waking the kids).
Here is my question. Rather than building a wall between the studio and the rest of the basement, I was think about using to large sliding barn/style doors (probably using reclaimed wood). Is this a bad idea in terms of acoustics as compared to a regular wall (drywall) and small door? Also, would this be a disaster in terms of noise leakage and defeat the purpose of insulating the room?
Sliding doors can be treated on the inside - so acoustically they are little different from walls........
Isolation however is a challenge - not necessarily one that cannot be overcome - but a challenge none the less.......
For example - at Sonalysts Studios - stages 7 and 5 have concrete filled sliding doors similar to barn style sliders - 20'x20', motorized openers (they weight several tons apiece) and they had to install inflatable seals to properly seal the openings (those 2 stages are some of the quietest movie studio/sound stages in the world - NC 15 ratings)
Now - with a door that was installed with an inclined plane track assembly - you could always do a compression set for the floor gasket and the leading door end - however - the top and tail end of the door would need to have gaskets that the door slid along - which means that their life would not be as long as it would with a compression gasket..... hence the use of inflatable gaskets........ especially for large doors.....
It is a challenge - but not impossible to make work. AS with most things related to acoustic isolation - the devil is in the details.
