11Hz, 18.98Hz & 23 Hz sine wave, infrasound speaker, light bulb, water, iron oxide, rubber, electronics

Infrasound Piece (2020). A very loud sound of three different sine waves below or on the threshold of human hearing range can be seen in the movement of water and in the flickering of a light bulb. Audible sound in the piece is mostly water drops splashing occasionally or intensely when low frequencies move the water. The water lays on top of a rubber covered infrasoundspeaker. The frequencies 11, 18.98 & 23 Hz can be felt as a physical pressure in the room.
