IIE is an interactive acoustic installation through which Reinhard Gupfinger researches infrasounds, that is, those sounds that, having a frequency less than 20/16 Hertz (20/16 cycles per second), are below the audible threshold of the human ear. While the ear is insensitive to those sounds, the human body can nevertheless perceive
them as vibrations. It is this possibility that the Austrian artist explores in this work, raising awareness of this relatively unknown curiosity. In fact, infrasounds are extremely common in nature, since they are emitted by atmospheric phenomena, such as thunder and wind, and by some animals (whales, elephants, etc.), which use them to communicate over distances.
