Untitled Sound Objects by Pe Lang and Zimoun is a series of works displayed as installation, performance and autonomous objects. Physical materials are made to generate sound by vibrating them using computer controlled motors, machines and robots.

One example of this (shown in the top two images above) is as follows:

Vibrating motors cause glass plates, on which various materials are placed, to oscillate. The vibrations move the materials and the frictions caused by this generate sounds, which are amplified via contact microphones and edited through DSP (Digital Signal Processing). Through a multiple channel speaker system amplified sounds are projected and reassembled into new sound architectures.

The artists’ aim is to selectively:

…mix between living structures continuously generated or evolving by chance and chain reactions on the one hand, contrasting with specifically delimited and contained space, in which these events are allowed to happen. Our compositional intentions are manifesting themselves through our deliberate containment and cautious monitoring. Thus, we are not busying ourselves with chance factors and generative systems in order to discover unexpected results, but rather to attain the vitality aspired in the compositions.
