Ok, so I have CHM and I am legally blind with some 5-10% visual field left. Alongside with the little vision I have left, I have a number of corroborative strategies to aid me in perceiving the space around me. Auditory and tactile generally. I don't know with any degree of certainty how exactly they work, but for the auditory strategies, it undoubtedly includes the primary sound sources from the environment and their location in relation to me when I move or the source moves, or both. However, echoes seem to be a rather large part of it all. In optimal environments, I can feel obstacles and approximate their distance. The tactile strategies I have even less knowledge how they work. I can feel vibrations emanating off of cars etc. and I can feel how air moves and deduce surroundings based off of that. Also, I can feel the body heat of people nearby.

Now, to the point. Why is it that my radars go haywire when the air is very humid? Even in moderately well lit environments I can't sense or even approximate nearby people's locations at all, and I have to REALLY pay attention when moving around in places where I usually can move rather freely.

And another thing that had a dramatic effect on my ability to move around was acoustic panels. It was a room meant for video conferences or something like that and it was almost scary. At first I thought my ears locked.

Are there studies about the phenomena I described? I'd love to know how exactly my perceiving my surroundings works and if I can further practice precision.
