Inmortal Egg is an Interactive Audiovisual Installation that I made in collaboration with Aniki Welt for the festival on Art and Technology FASE6 in C.C.Recoleta Buenos Aires, Argentina, which is based on the research of binaural beats and how they affect our brain.
We programmed this work with the Processing environment in order to induce certain mental states associated with different types of body sensations, ranging from full alertness to states of maximum relaxation.
The user has the choice to select between three types of desired states: creative, meditative and active.
To do so, the user enters alone into a white immersive egg shaped cabin of isolation, provoking a primitive state that allows a greater degree of engagement.
The sound waves are triggered through one pair of headphones, implicating an intimate and individual connection to the work and oneself. At the same time, the user is immersed in a beam of light that vibrates and flashes to the exactly same binaural frecuency, increasing the effect generated by the sine waves.
A binaural beat is an auditory illusion perceived when two different pure-tone sine waves, both with frequencies lower than 1500 Hz, with less than a 40 Hz difference between them, are presented to a listener dichotically, that is one through each ear.
For example, if a 530 Hz pure tone is presented to a subject's right ear, while a 520 Hz pure tone is presented to the subject's left ear, the listener will perceive the auditory illusion of a third tone, in addition to the two pure-tones presented to each ear.
The third sound is called a binaural beat, and in this example would have a perceived pitch correlating to a frequency of 10 Hz, that being the difference between the 530 Hz and 520 Hz pure tones presented to each ear.
