A medida da voz needs to be installed in an open space, on a land that can be dug, so without many roots or stones. The color of the earth has to be the same as the color of the clay vases. The size of each vase should be around 75 x 30 x 90 (high) cm, having the format of a cone. Each one of them has a sound box inside, which caries a specific channel of sound, a specific voice. The entire installation is a circle, I type of mandala, and it should measure around 6 meters in diameter.
