Sound transfer between houses and offices having common walls is a common problem. Lack of mass in the cheap constructed walls has resulted in this problem. The sound transfer occurs as a result of airborne noise (voices, music, etc). The airborne sound wave strikes the wall and the pressure variations cause the wall to vibrate. This vibrational energy is transferred through the wall and radiated as airborne sound on the other side. Breaking the existing walls and rebuilding new thick walls is not a possibility and hence soundproof partitions are required to be built in front of the existing walls to address the issue.
