Graduation with pneumatic installation translating soundwaves into movements (ArtScience)

My starting-point of this graduation project (Artscience KABK, former Interfaculty Sound & Image) was to meet IMAGE (3D-movements), through (an analyse of) SOUND , with a triggering between both. I took away the abstract soundwave from a display and made it visible, audible and real. I tried to make feedback visible to avoid the installation being just air.

To translate soundwaves into 3D-movements I used 5 pneumatic pistons, whose movements corresponded with the changing figures shown by the oscilloscope. So the pistons are showing realtime the movements of the audible soundwaves by going up and down. The image of the soundwaves was also projected on the pistons with a beamer. This made the shadows play and closed the beginning and end of the cyclus.

The installation was triggered by original soundrecordings of the cylinders, valves and compressors itselves. That means that they reacted on their own sounds (4 channels, 50 samples, live mixed with live sounds directly from from the microphones). Feedback with me as conductor in between, which closed the circle in sound. However, each sound-input would be optional, as wel as complete self-acting behavior without any need of a human being in between.

Krankenhaus can be considered as an experience-artproject in the environment, an electronic / pneumatic concert of original sounds, live pneumatic noise, with the original changing images of the oscilloscope used as input signal resulting in the industrial show of the pistons, going up till 2 meters high, originally made to lift 1000 kilo's each, were just dancing in the air. This made a strange real / unreal impression.
