Acoustic wallpaper is going to make a minimal difference to the amount of sound getting into your room, however if all you are looking for is something to turn down the ambient background noise of some distant traffic or chatting then soundproof wallpaper could make enough of a difference to be worth considering.

Acoustic wallpaper works by layering, instead of just being made up of a simple patterned sheet like most wallpapers is.

Acoustic wallpaper is high level wallcovering which could make a very high level home environment.
