‘Biophonic garden’ raises questions about the communication of plants.
An experimental laboratory setup is used to display a possibility to make a dialogue between corn seeds perceivable for the human ear. Sprouted corn seeds are arranged in a grid which is situated in a container filled with water. The acoustic environment beneath the seeds is being recorded by an underwater-microphone, which allows visitors to listen to the dialogue between the seeds. While the roots of the plants are submerged in the water, a constant sine tone of 220 hertz is played into the water. It seems that this has an influence on the growing process of the roots, which bend towards the sound-source.
