1. Capturing the acoustic emissions of the corrosion process in an icon of steel. The inaudible, ultra-acoustic cracks refer to a world under stress.
    Listening to the internal activity of solid structures reveals the transformatory nature of infrastructure, a metastability.
    Every new acoustic emission is concatenated to the audioloop: an initial loop of one or two crack sounds is extended with each new event so that multiple micro-melodies arise.

    In collaboration with Dr. Helge Pfeiffer, Johan Vanhulst and Michael Stamm from
    Department of Metals and Materials Engineering (MTM) of KU Leuven University

  2. CELL is an installation that consists of a steel cylinder (Ø 160cm; H 250cm) which is freely accessible and of a web of wireless sensor blackboxes. On several spots these sensors measure fine vibrations that occur within the building or in the environment. The steel cocoon receives those vibrations and amplifies the low frequencies across its inner surfaces. Sound is distributed over the steel surfaces through six to nine powerful transducers which are mounted inside the double cylinder shell.
    The work acts as a focus point of contact events between bodies and architecture. As soon as vibrations resonate with the steel they are registered and stored. The events recorded are looped and slowly rise in pitch over time. The cylinder assumes the function of a repository for infrastructure vibrations, while producing a moaning melody coloured by the steel’s resonance. The melody is always in transformation as it is combined of pitchshifted tones and the arrival of new low energy content from realtime vibrations.
    All low frequencies evaporate after some hours when they have lost all of their materiality and they leave the steel sculpture’s memory as high-frequency remainders.

  3. Language is a collection of either sonic or visual objects that are structurally related to one another and thus create a system that has significance for the user of that system. For the uninitiated this code produces no semantics and only the aesthetic form and sometimes the exotic appeal of the language remain.

    LANGUAGE I consists of a compilation of individual speaker cones that are put under tension. There is no audio signal, but the electrical voltage makes the cone expand to its maximum for a fraction of a second.

    The sequential on and off switching of a defined set of elements can be described as the formal prerequisite for language. Language is a collection of discrete elements that can be combined according to certain rules. The minimal set of building blocks are phonemes (sounds) or symbols: letters (alphabet) and numbers (machine language).

  4. A 13 minute video by Rui Ribeiro documenting a presentation of the Staalhemel installation in the central Horta hall of Bozar, Centre for Fine Arts in Brussels.
    This video focuses on the experience of the visitor. Different facial expressions reveal inner reflections of visitors that are in interaction with the machine.

  5. In the interactive installation 'timecodematter' the visitor enters an arena that is bordered with vibrating sheets of massive steel. The steel objects are pulsating with low frequencies and they react to the approach of persons. The acoustic energy in this installation is both penetrating and intangible: the resonant properties of twelve different steel sheets respond to the low frequencies and produce a conjuring effect.

Christoph De Boeck co-founded the collaborative structure 'deepblue' in 2002 together with Heine Avdal and Yukiko Shinozaki. From within this production structure he engaged in many productions as a sound artist, sound designer, and electronic musician.
De Boeck aims at rendering sound tactile through spatialisation and with alternative choices of sound transmission, like transducers to incite steel resonance. For concerts in multichannel audio set-ups he often teams up as Audiostore with Eavesdropper/Yves De Mey.
He collaborates with biomedical scientists on the sonification of brainwaves in the art&science project 'Staalhemel'/'Steel Sky' (2009).
