Text, pictures and audio by Joost Van Duppen

Vallisaari May, 26 2018 – #Resist Like A Forest

We chose a place where we observed the environment daily at the same time for half an hour by researching macro & microscopic relations between natural & human elements.

Vallisaari, despite being a nature reserve, is disturbed by many human activity that are not immediately audible and visible to our senses.

In the graphic representation you can see the contrast between human and natural activity.

There is a clear low frequency around 100Hz, this is probaly due to the heavy engines of boats. Here after you can listen to 10 minutes binaural sound recording.
