Sound Stem
2017

30 speakers, 30 pre amps, 8 x 8 m net, 120 bicycle spokes, 60 rubber bands, HDF hooks

“Sound Stem” is exploring the Amazon rainforest sounds that we usually cannot hear. These sounds are produced by the Amazon rainforest plants, animals, insects and birds. The work is a part of my research on communication among plants, insects and birds. Goal is to find a way to preserve forests after the extinction of wildlife in the future. This artwork explores tree produced ultrasounds. William J. Mattson and Robert A. Haack in their paper “The Role of Drought in Outbreaks of Plant-eating Insects” suggested that insects can hear a tree produced sound emissions. The sound emissions in a tree are produced during the cavitation process – when the water from ground is going up to the tree branches it makes sound in the range between 20 kHz and 2000 kHz.

I went to the Amazon rainforest to record sounds from around 30 trees. I used these recordings to try to find the sounds that might be made by cavitation. In my notebook I marked the pattern of recorded trees (how far the trees were from each other). During an exhibition each tree is represented by a parabolic speaker (which makes the sound audible only in one particular place, like a shower). Speakers are set up in the same pattern as the trees in my notebook and hang from the ceiling. By walking through the installation and stopping in particular places a visitor is able to hear the sounds produced by each of the 30 trees in the Amazon rainforest.
