In the forbidden city in Beijing there is 2 monuments that are round an have interesting acoustic properties.
The first is a round marble covered area enclosed with a marble balustrade. When you stand in the centre an speak out loud you hear your own voice in a way you have not done before. You voice feel like it carries a long way. You feel like and emperor :-) The second is an round outside area enlosed with smooth walls, if you wisper close to the wall the sound of your voice is spread along the wall.
