I'm making a door for a sound booth out of pine 2x4's and drywall that's
going to be about 44 1/2" wide, about 78" tall, 4 1/2" deep. The depth
includes 3 1/2" for the 2x4's and 1/2" drywall on each side.

Along with the frame of the door will be a couple of internal support
members and R-13 insulation. So, it's going to be fairly hefty. My seat of
the pants guess is it will weigh around around 80 - 100 lbs. give or take.


Seems an odd design for a sound deadening door. Drop the insulation.
Get a regular door and glue the sound insulating cones on it. I have
been in sound chambers at work and this is how they do it. Of course if
you are carrying on a ruckus you could damage the cones... from what I
hear thermal insulation is not very good at sound insulation at all.


In selecting hinges, should a 3-pack of 3.5" hinges from Home Depot do the
job?


Your door is so light it should not be a problem.
