THE “MIRROR
EFFECT” IN SOUND’S FUSION TIME: THE INTEGRATION OF TWO SPECULAR
SOUND FIELDS IN ONE MENTAL-VIRTUAL HOLOPHONIC SOUND FIELD. PHENOMENOLOGY AND
APPLICATIONS.

This integration solves the information’s
paradox expressly produced by the system structure itself. As a matter of fact,
taking into account the physical and acoustic dimensions only, it would be
impossible to distinguish the front sound emission from the rear one. However,
the listener’s mind is able to reconstruct a three-dimensional space
experience and thus to distinguish between front and rear sound fields.
We hypothesize that the capability to fusing
and reconstructing sound information in a “virtual” holophonic
field is related to a peculiar way to elaborate the space experience, which is
also active during dreams. Dreams exist in a specific dimension of mental
experience, that we define Primary Mental Space.
In order to verify whether, in the absence of
recognizable sound structures and with closed eyes (Setting a), the mind
is able to produce any structure in the primary mental space, we
utilized a correlated, fractalic structured sound (1/f, Pink Noise). An
autopoietic mind’s property emerged, producing images and sounds
(different from the stimulus) with a degree of realism close to the perception
of reality, in a statistically relevant number of subjects (25% during a single
listening session, 80% throughout six listening sessions).
The phenomenology of mind’s autopoietic
productions suggests an increase of information exchange between neocortical
areas and older ones.
EEG’s analysis allowed us to observe
during listening sessions a brain’s tendency to produce synchronizations
in all the bands (a,b,d,g) and in all the cortical areas.
Although a direct relation between cortical synchronizations and mind’s
autopoietic productions cannot be presently demonstrated, we hypothesize that
the increased performances of both mind and body reported by most subjects
(insight experiences during and after the session; physical activation after the listening session) could be
related to an increased plasticity of neural paths induced by these general
synchronizations.
The phenomenology of the autopoietic
experiences should be further investigated from the perspective of the human
tendency towards meaning making, independently of conscious intentionality.
