The installation MOSQUITO HARMONICS describes another subchapter of the long-term project UNVEILED PRESENCE (secret sounds). It deals with ultrasound tones inaudible to the human ear, arranged in space like a classical mobile hanging from the ceiling. The single parts of the mobile consist of ultrasound generators, which are moved by thermal and air circulation. The acoustics are translated for the human listener by a bat detector, which can be positioned at different positions in the space and makes the kinetically modulated twelve-tone composition audible.
