Shared Wall Noise in Duplex

[Jed Massey]

Purchasing a duplex, while walking through with the home inspector. Couldn’t help but notice that I could hear the other tenant through a shared wall of the duplex. I’ve been brainstorming whether to dig into the drywall. And then maybe apply liquid foam insulation. Or maybe dig into wall and see if there is any insulation at all and then insulate it. Or maybe double drywall that wall and then mud.  Or maybe even a combination of some of these. Has anybody approached this problem with any different solutions? Let me know what you guys think.

Masonry walls aren’t required everywhere. There are sound proofing measures that can fix this, but the absence of masonry isn’t immediate cause for alarm.
