Alex Metcalf’s Tree Listening Device is small, metal, conical, mobile, and allows the listener to hear the inner-workings of trees.
By placing the device against the bark of your chosen tree and placing your ear at the other end you will hear the water being pulled up from the roots to the leaves through the xylem tubes. The clicking sound that you will hear is produced by the water passing through the cells and cavitating.
He’s also created an installation piece in which headphones are attached to sound sensors and draped from canopies. No trees are harmed in the makings of this piece.
What a positively enchanting piece of work, no? I wonder if the insides of different kinds of trees sound very different?
