about

Daisuke Ishida explores space solely by means of sound. The artist creates and shapes architecture, the forms, boundaries and volumes of which are strictly of an acoustic nature.

An omnidirectional loudspeaker buried beneath the ground of Friedrich-Wilhelm-Platz creates a hemispherical sound space, the size and tension of which is defined by the loudness and sound patterns emitted. Set within a busy public space with heavy traffic, the artist prompts active listening in the passer-by by introducing synthetic sounds with no evident source, that stand out against the urban acoustic signature. Through this accentuation the listener is made aware again of the daily urban soundscape.

about

Daisuke Ishida explores space by forming it through sound. He tries to create architecture by acoustically defining its actual spatial boundaries. “Acoustic Octahedral Geometry” facilitates a tangible experience of such a space.

The room’s borders are sculpted by twelve thin sound lines, produced by super directional sound. This takes advantage of the extreme focus of super directional speakers and the reflective properties of its output sound. The space can be observed through sound propagation and variations of sound patterns over time. Therefrom emerges an invisible geometric architecture – the beams and their reflections form an octahedral room in space. Within this, the weight of the sound field energy is shifted via sound patterns to enable an experience of this space’s dynamics.

The spectator may visualize the eight faced shape and is able to interact with the geometry by crossing one or more sound beams and therefore reflecting it with his/her body. These interferences form new invisible lines and change the overall shape temporarily.

about

The use of motors and the constant increase in private and public traffic have fundamentally changed the sound character of our environment. These kinds of noises, and even more so the intensity of the sonic burden, have multiplied so that city life these days means being permanently surrounded by traffic noises. Whether we are aware of it or not, we have grown accustomed to this ambience and more or less accept conditions as given. Only when these sounds are suddenly diminished or absent, such as when we travel and find ourselves in a completely different environment, do we notice how pervasive they normally are.

In Daisuke Ishida’s installation Vordergrundgeräusche (Foreground Noise) the ambient sound, as well as sound pressure level, is visualized through lights placed along the arched passageway of the Art University building. The lighting functions as an indicator of the measurements in real time and brings attention to the existence of ambient sound as well as its dynamic changes. In this way the beams of light begin to turn background noise back into foreground noise.
