Soon I'll be moving into a new house where I want to set up a home theater.
The house has direct neighbors on both sides, but is relatively new (built +-10y ago). Between the me and the neighbors, there is 2x 15cm silicate stone (1750kg/m3) separated by 2 cm mineral wool insulation. The sound transmission loss, according to this site is:
I would like to know if these are "good" values, or if I should be looking into adding extra insulation in between? When I measure my music volume I currently enjoy when it's a bit louder, I get +- 70dB, measured with an Android app. Not sure if that is relevant.
