Some post by Tima about our brains made mine stir.
Perhaps this one, below ... it is more about listening than your topic, but happy it stirred your brain.
Assuming one can hear, hearing happens. Sound pressure waves act upon the hearing system and the brain receves electrical signals from the ear. You don't need to be awake to hear.
Listening is intentional. One intends to receive sound, one is receptive to sound, often specific sound. One may hear sound that is other than the specific sound one wants to hear and that is distracting and yes, can divide attention or break attention to specific sound.
Undistracted listening may either be focused or unfocused. Focused listening occurs more in the cerebral cortex - cognitive listening. Listening can also occur at what we might call an intuitive level, a non-cognitive level that is rooted in primitive limbic functions of awareness, deep in our lizard brain.
Imagine yourself talking with a friend while walking through a mall during the Holidays. You hear all sorts of sounds from all different directions but you are able to ignore those and listen to what your friend is saying. All of a sudden a musical group starts to play handbells and sing. Immediately, without the type focused listening of hearing your friend, without cognition, intuitively you know that is the sound of live music.
Sitting before your stereo, when one 'let's go' or loses focus while listening to music, consonance and dissonance will light up limbic systems responsible for pleasureable and negative emotions. The non-cognitive experience of music can trigger areas in the brain sufficient to cause the release of endorphins -- when they reach the limbic system’s opioid receptors, feelings of satisfaction ensue.
The intuitive/cognitive balance can go both ways. If a component or a system breaks the fundamental rules of human hearing, our music-listening brain reaches a kind of tipping point where processing of music occurs less in limbic areas and more in the cerebral cortex. While listening to my stereo, if my ear/brain system detects distortion, for example an excess of third-order harmonics that cause increased loudness or forwardness from that trumpet section over there in right field, in an instant it can happen: focus is triggered, the eyes open and the non-inferential immediacy of our musical enjoyment collapses.
I think a level of high quality playback can shock a listener out of reality and into a space with the music where the intent of the artist has a chance to dwell up emotions. This can happen any time with any old radio. But a heaping dose of HIFI clarity and bass gusto or a Natural sound might help loosen ones attachment to reality for a moment and let them move to other places in their mind.
Perhaps you are thinking of non-cognitive limbic listening as a "loosening of reality".
