What does a forest really sound like? Join a group of acoustic aficionados, tree specialists, and others for a field trip deep into the Bay Area’s redwood ecosystem to monitor, record, and listen to giants.

In tandem with the trees: Downy Oak exhibit at swissnex San Francisco, project leaders Marcus Maeder, from the Institute for Computer Music and Sound Technology at the Zurich University of the Arts, and Roman Zweifel, of the Swiss Federal Institute of Forest, Snow and Landscape Research, lead a small group of participants to Muir Woods National Monument in the Marin Headlands to demonstrate their field work methods and capture the sounds of the forest.

For the trees installation, Maeder and Zweifel turn the woods into an audio adventure through recordings taken with an arsenal of specialized microphones combined with data measurements such as humidity and sunlight. Their not-to-be-missed Muir Woods field trip allows participants to experiment with their techniques, made possible through the kind support of the National Park Service. Participation fees will be donated to the NPS.

Marcus Maeder

Marcus Maeder studied art at the University of Applied Sciences and Arts of Lucerne, in Switzerland, and is currently pursuing a master’s degree in philosophy at the University of Hagen, in Germany. Maeder runs the music label domizil, which he co-founded in 1996 with Bernd Schurer. He has worked as an editor and producer for the Swiss radio station DRS and has been working as a curator and research associate at the Institute for Computer Music and Sound Technology since 2005. His artistic work focuses mainly on sound art, and on media art extensions of computer music. Maeder has also written on a number of topics in the fields of sound art and digital media.


Roman Zweifel

Roman Zweifel studied biology at the University of Zurich and at the Swiss Federal Institute of Technology in Zurich (ETH Zurich), where he received a Ph.D. for his ecophysiological work, “The rhythm of trees.” Zweifel’s research has focused on whole tree gas exchange, mechanisms of water flow and water storage in trees, and using wood anatomy to link water with growth and carbon balance. He is significantly involved in how continuously measured stem radius changes are mechanistically coupled to growth and tree water relations, and his current research activities are focused on linking tree physiological processes with the processes on the forest ecosystem level.
