Jacob Kirkegaard has turned his listening ear inwards – to his own ear. By using specially developed listening equipment, he has captured the microactivity which the hair cells of the ear send out.
LABYRINTHITIS consists entirely of sounds generated in Jacob Kirkegaard’s own ears. Deep inside the cochlea there are thousands of microscopic hair cells functioning as sensory receptors. When sound enters the ear, they begin to vibrate in the watery liquid surrounding them, like underwater piano strings.
Thus, the hearing organ does not only receive sound. It also generates sound, just like an acoustic instrument. Some of the hair cells in the cochlea can change their shape to such an extent that they are enabled to move the basilar membrane and produce sound themselves.
These faint tones resemble the sound of a tinnitus – and they can be recorded with a microphone in the ear canal.
Jacob Kirkegaard employs the 1787 auditorium of Medical Museion as well as the audience for his composition: His listeners become part of an interactive concert as their own auditory organs respond to the tones played out into the auditorium. The room, at the same time, turns into one big resonant labyrinth of sound.
