Project

Frequency and Volume enables participants to tune into and listen to different radio frequencies by using their own bodies. A computerised tracking system detects participants’ shadows, which are projected on a wall of the exhibition space. The shadows scan the radio waves with their presence and position, while their size controls the volume of the signal. The piece can tune into any frequency between 150 kHz and 1.5 GHz, including air traffic control, FM, AM, short wave, cellular, CB, satellite, wireless telecommunication systems and radio navigation. Up to 48 frequencies can be tuned simultaneously and the resulting sound environment forms a composition controlled by people’s movements. This piece visualizes the radioelectric spectrum and turns the human body into an antenna. All the receiver equipment used and antennae are exhibited in an adjacent room.

Materials

Projectors, cameras, computers, radioelectric scanners, antennae, radios and 48 channel sound system

Technology

Frequency and Volume invites visitors to tune in and listen to different radio frequencies by using their own bodies in an interactive video and sound installation.

Effects

In the artwork, a computerized tracking system detects visitors’ shadows, which are projected on a wall. The position and outline of the projected shadow determines the frequency scanned, and the size of each shadow controls the volume. The public and private radio waves become visualized as a data space. The installation can tune into any frequency between 150 kHz and 1.5 GHz, allowing visitors to hear not only to FM and AM, but air traffic control, short wave, cellular, satellite, wireless telecommunication systems, and radio navigation.
