Documentation for the audio installation:


A silent labyrinth created out of open copper trails
on the floor carries the electrical signals of a
multichannel sound repository.
By putting wireless speaker- cylinders on them,
the carried sound layers can become audible and
the interpretation by the visitors gets possible.
The "Offener Schaltkreis" reacts depending on the
manner in which the speakers are used: If nothing
is moved, the sounds stay calm and soft, but as soon
as a single cylinder is placed elsewhere, the sounds
of all speakers intensify simultaneously.
This results in a dynamic relation between
silence and noise, which is influenced by the visitors.
