I just built a room for my children to use for band practice. I want to keep the noise in the room not to disturb the neigbors and myself in the adjacent room. At this point the room is un finished wooden studs with no insulation or drywall. Fiberglass insulation is not enough for sound proofing. Is there a material I can put between the studs that would do the job. The room is the second floor of my garage. The floor is insulated but still noisey in the garage. What floor material or garage ceiling material can I use for sound reduction.
