Description – Sculpture, Hacked object.
Details & Scale: 10 inch CRT, Amplifier, MP3 player.(2016).

The range of 20 to 20,000 Hz is what is audible to the human ear.  Any sound lower or higher than that frequency cannot be perceived by humans.  Machine 20-20k Hz visualizes these frequencies over a duration of 19 minutes and 20 seconds as an audio signal is sent through an amplifier connected to a CRT television screen.  As the frequency rises from 20 to 20,000 Hz over the duration of time, the soundwave shown as output on the screen changes with it.
