“Listening to sound is where objectivity and subjectivity meet” 
In Voegelin book Listening to noise and silence, she discusses a liminal quality found in listening. She describes listening as an experience of our perception. The listener produces objectivity from the subjective listening position. Objective thought is what we take to be the objective world. For example a computer screen, the table etc. A subjective thought is what we take to be our narrative thinking or imagination. For example the thoughts you have while listening.
I consider listening to sound is an in-between experience. Sound can be activated as a disruption, or incursion, in-between the objective and subjective experience. We can describe this disruption as being in-between mind and matter.

I have searched for In-between categories found in the audible world. In Asenjo book ‘In-between: an essay on categories, He believes contradictions should not be eliminated or modified as they provide “an ‘opportunity for a richer, two sided development of factual meaning.’
I consider soundscapes create an experience that opens up the possibilities of in-between-ness. Within an immersive soundscape, a dynamic interplay of in-between categories happens, for example, cause and event, objectivity and subjectivity and feelings in-between the strange and the familiar. The In-between categories found in sonic realities are not fixed points, for example; in-between presence and absence. Our perception moves or flows in-between these two points.
