Stc sound rating

2. Cavity Absorption. Adding more insulation can have a profound effect on a wall assembly’s STC rating because it adds sound-absorbing material to the assembly. In the examples below (figures 6 and 7 in The SoundBook), going from an uninsulated wall to an insulated wall boosts the STC rating 8 points.

STC rating (Sound Transmission Class rating) is a score given to a building’s surface (wall, ceiling, window, etc.) based on its ability to reduce sound coming … “An STC rating roughly equals the decibel (dB) reduction in noise volume a wall or partition can provide. For example, if an 80 dB sound on one side of a wall/floor/ceiling is reduced to 50 dB on the other side, that partition is said to have an STC of 30” Source : Minnesota Sustainable Housing Initiative Consider installing a whole-house audio system and the music in your home won't stop!
