How to make walls sound penetrable?
By drilling a series of small roles and covering one side with a membrane, such as cling film, you can effectively capture the sound from the other side of the wall on your side. "The wall with the bare holes seriously hinders the transmission," said the scientists in the June 13 issue of Physical Review Letters. But with the membrane installed the transmission becomes, as expected, almost as good as with no wall." This practice is based on a concept called extraordinary optical transmission, a process in which sound finds a way through a surface through which it would normally be reflected.
How to use stemless glass?
Its a cliche, but it works. Take a stemless glass and place the open end against the wall.

Bernard Ryan told the press; "It sounds silly, but we put a glass to the wall to try to work out what was being said. It worked - we could hear them shouting 'there's no more money in the house'. I didn't have a second to be frightened."
