The Swiss Pavilion in Hanover Germany represents continual change and renewal. The Swiss Sound Box can make a total of 153 sounds and 23 eruptions. The sounds tend to spread out in the open area and the eruptions are loud, rhythmic, and non linear they surprise the listener. Sounds and eruptions appear in a pattern, based on a different schedule every day. The walls work like instruments themselves because they increase the volume, conduct it throughout the building, and amplify it.
