rares_spaces #1  //  discovering infinity 

rare_spaces  is a series of artistic investigations of the acoustic potetntial of spaces that are normally not accessible for the public.


The tools for this research are loudspeakers and microphones, while the experiments focus on the natural resonance frequencies and the reverberation-time of the individual space.


The investigation methodes are controlled acoustic feedback and impulse-responce experiments.


Each investigation results in a 10-15 minutes audio-piece that is an acoustic portrait of the individual space

In 2013 we manages to get access to an abandoned spherical gas tank for one day to conduct acoustic experiments.


The acoustic properties of this space were that impressing (0.5-seconds bounce-back echo and a reverberation-time of almost one minute) that we decided to search ror more such spaces.


The initial plan to further work with this unique space was nullified by its demolition in late 2013.


Nevertheless, this was the starting-point of the rare_spaces series.
