As with all direct to wall acoustic boards, the SoundBoard 4 and Soundboard 3 are not recommended for impact noise.

if you are trying to block impact noise (such as doors slamming), or lower frequency noises such as the bass sounds from music, computer games, or the likes of deep voices or snoring then the recommendation would be to use a solution that decouples the soundproofing from the original structure such as the ReductoClip system
