Stumbled upon a fascinating study having to do with the interactions between sight & hearing
http://www.pnas.org/content/early/2018/01/22/1717948115.full
These observations suggest that a vision-related process modulates the first stage of hearing. In particular, these eye movement-related eardrum oscillations may help the brain connect sights and sounds despite changes in the spatial relationship between the eyes and the ears.
The article is very technical, but here's the basics
Our eardrums are constantly moving and adjusting based on our vision sensory input, even with NO sound present, so technically our sight is the first step in "hearing" as far as our brain processes go
These eardrum movements, which we dub eye movement-related eardrum oscillations (EMREOs), occurred in the absence of a sound stimulus.
So if visual stimulation has such an impact on how and what we hear, Could exposure to certain visual stimuli artificially increase our enjoyment of music?
what about visual stimuli that sets us up to not enjoy music as much? I have always wondered about the fight or flight response because loud and sudden noises can actually trigger the brain to "protect" This can possibly change hearing ability
This study demonstrates for the first time that the cochlea – a small, snail-shaped organ that's part of the hearing system, alerts the brain to produce CRF to protect itself when exposed to loud noise. You don't have to think about it – it just happens, just as the fight or flight reaction kicks in whenever we're faced with perceived danger or stress.

What are your experiences with this phenomena? I will try to keep a record of times I feel like I'm hearing "differently" based on what i saw or did previous to listening.
Between our own actual hearing ability, placebos & bias, and now the fact NON audio stimulation can change the way we hear, are we even hearing the music?
