Replacing my plaster walls

[2manyrocks]

Did someone just do a bad plaster job that's not correctable at low expense?

Kind of. I think they are very ugly and ultimately I'm trying to justify a reason for tearing them out and having nicer walls. I won't do it unless having the fiber insulation and drywall combo or something else will change the sonic quality of my room for the better though.

I hope someone else will correct me if I'm wrong, but I don't see a significant acoustical advantage to tearing out your existing insulation and plaster wall to replace it with fiberglas insulation and drywall. If you are having problems with reflections in your space, you would typically put up acoustical panels inside the space to reduce them. The panels might cover over some of the ugly without tearing out your walls.

If you tear the plaster wall out for reasons of appearance, I think you'll still end up having to install acoustical treatment inside of your space.

If external sound is coming into your space from outside your existing walls, that presents a different matter of isolation which might require more drastic measures to correct (double stud walls of drywall/insulation/air space/insulation/drywall).

I"m a little hesitant to suggest this, as I'm not a acoustics guy by a long shot, but have done my share of drywall and hate it...so...there are many options for covering ugly walls from textured materials to types of tiles that may give you some slight acoustic advantages and would be less expensive and less work than building new walls. If as said, you need more isolation, then building new walls inside of the existing walls is still less work and mess and would give you a quieter space. A trip to the local lowe's or home depot might give you some ideas.
