The answer depends manily on materials of wall.

Since sound wave is transmitted by vibration of air particles, solid wall with less air particle inside (i.e.實心) is less effecicient in transmitting sound waves to the other side, though it does occur.

Incomparison, a hollow wall (e.g.夾板牆) which trapping numbers of air particle inside. Thus sound wave is transmitted to the other side of the wall much efficiently.
