I practice massage therapy and sub-lease space at a wellness center. I can clearly hear the chiropractor talking next door and the acupuncturist walks around like a clumsy elephant. The floors are hardwood, the walls and doors are hallow. My room also shares a wall with the kitchen/break room, so I hear when people wash dishes in the sink. I have been told that removing the existing drywall is not an option. I read about slow rise foam, but I'm understanding that the rigidness of it is ineffective. What about "blown-in " insulation? Replacing the hallow doors with solid core doors may be a possibility, though I want to be cost-effective. Please help.
