The sound art was shown in 2021.

As humans we have limited senses to perceive nature. One of such is our audible range, which is incapable to detect frequencies below 20Hz and above 20kHz. However, sound penetrates our bodies not
only by our ears, and those frequencies can be perceived through our skin, bones and resonating cavities of the body.


Without noticing, we are daily exposed to multiple sources of infrasound and ultrasound from natural phenomenon to home appliances, frequencies that we can’t hear but clearly have an impact in our bodies and influence our wellbeing.


Limen aims to unveil the invisible sounds of our everyday life. The piece works around the fluorescent lamp, one of the most commune sources of light which also produces many tones above 20kHz. Using a special microphone we captured those ultrasounds and translated them into audible frequencies.


The composition uses only those invisible sounds produced by the lamps. This sonic material triggers a choreography of light composed by 128 fluorescents which are displayed in the shape of their ultrasonic waveform. The sculpture is surrounded by a yellow filter, a color known by its ability to increase our concentration and perceptional capacity, enhancing other organs than the ear on sensing those frequencies.

Limen was created during a two-months residency realized in collaboration between Creative Industry Košice and KAIR- Košice Artist in Residence.
Supported by Klangraum Krems Minoritenkirche and in cooperation with AIR – Artist in Residence Niederösterreich.
