The Sound Installation

What does the earthworm say to the springtail when they meet beneath the carrot field? Can you hear grass growing? What is the difference in sound from a vegetable field with organic soil and one with conventional ones? Visit the sound installation «Sounding Soil» and answer the questions yourself:


When and where?


15th of august – 15th of september 2022: Ebenrain Centre for Agriculture, Nature and Food in Sissach, BL

The walk-in installation, housed in a shipping container with a 3D Surround Loudspeaker System, makes you feel as though are in the soil and walking between the roots and animals. Visitors can touch the various screens to hear a range of soil recordings.

The sound installation, developed by the artist and researcher Marcus Maeder, makes it possible to experience two basic things. First, you can listen to the incredibly diverse life in the ground. Second, the differences between soils can be clearly heard: a healthy soil with high biodiversity has more sound variety. The installation gives a sensory experience the soil and builds awareness of the human impact on soil organisms.
