Adding soundproofing/insulation to interior walls
I just recently moved into a new home, and the builder installed 1/2″ drywall throughout the house. On the exterior they put fiberglass batts but nothing on the interior walls. The hollow stud space with 1/2″ drywall seems to almost magnify the sound from the next room. What can I do to add some soundproofing to my interior walls to help quiet the house short of tearing the drywall out of my new house. Thanks!
