Sub-leasing space at Wellness Center

[weaving1]

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.
