What is interesting for the wall lies in the fact that if one person speaks or even whispers at one side of it, another would be able to hear rather clearly on the opposite side.
This is because of the conductibility of sound waves; the wall itself has eaves and is hermetically laid. These factors are supposed to let human voice "travel" round the wall easily.
