The single audition

Sensory systems are inputing systems, but with a broader view that allow us to develop from each sensory system (namely the auditory & visual systems) an input/output system we might observe different sides of the story.

The Auditory:
Outputting: will be largely from voice and to a little extent from gestures from hands or whatever.
this input/output acoustical system is very useful in communication as we can easily observe.
This enables one to be effectively affecting the outside(people for example) from the inside(inner thoughts)

The visual:
outputting: how to define a visual output??!
