Stream Groupings X-XX
This little electroacoustic installation piece is comprised of a series of complex micro patterns made from two simple but distinct alternating streams of finely tuned sine wave sound events. It is an experimental situation to test the Auditory Scene Analysis (ASA) Paradigm proposed by Psychologist A. Bregman, and it is as well a collection of wondrous little loops in their own right. In Auditory Neuroscience or Psychophysics, ASA is concerned with the auditory perception and organization of sound elements into a meaningful entity that is closely related to discoveries in Gestalt Psychology. It includes the abilities to break an auditory stream of sound propagations into distinct elements across the time and frequency domain through segregation, grouping and integration. Here i used several streaming methods to demonstrate and organize the various psycho-acoustical effects, from alternating tones, that group into ghost melodies, to the complex “galloping” rhythm effects caused by fast sound alterations that expand into perceptual occurrences of more than just two streams or complex melodies and time domain based patterns. The pieces are diffused on one speaker projecting sound onto a hard surface to further introduce spatial complexities. 6-9.07.2011, Starkart, Zürich, Switzerland.
