cool to hear - I have existing rooms that I replaced hollow core doors with solid core doors, but it didn't help much. I thought I would have to rip off gyprock to add better sound insulation, but maybe just adding another layer might help...
I assume it would only have to be on walls adjacent to other rooms, ie not exterior walls? And how did you really know this worked? Did you ever live in a room like that, or try this on someone who reported it helped back to you in some fashion? Thanks for the idea :D !
