The proverb says: "As the call, so the echo" - but that's not quite true. Echo returns only as many syllables as fit time in shouting distance - the wall - flashy. This explains the reduction of words such as "Ma-jester-ka" - "ut-ka" "But-in-village" - "on-villages". For the occurrence of multiple echo must be some reflecting walls. A special case is a reflection of the so-called "corner whispers" that often demonstrate in old churches or castles. Talking to a certain point of the room can be heard in one or more precisely designated locations. In the simplest case, the builders used the reflective properties of the ellipse. Often you can find in the novels of stories about how the corners are used for eavesdropping whispers of all sorts of secrets. However, most likely the corners of Whispers is not the fruit of evil intent of the architect, but the consequence of the random design features.
