Acoustic insulation can have an R value, which relates to how well it thermally insulates the home, but you should be aware that the R value has nothing to do with its acoustic properties. You will need to install additional thermal insulation if your acoustic insulation does not meet the minimum requirements.

Also question is, what insulation is best for soundproofing?

Insulation. Loosely packed fiber provides excellent sound absorption, which is a factor in soundproofing, albeit a minor one. Standard fiberglass insulation is as effective as mineral wool, and much less costly. Foams give great thermal insulation but are actually poor for soundproofing.

Does acoustic insulation work?

Common fiberglass insulation Fibreglass insulation does offer some absorption qualities that are useful, and like soundproof wallpaper, may be able to reduce the sound of mid-range frequencies. But in terms of soundproofing a room and significantly lowering the noise levels, it doesn't offer much help at all.
