> This perceptual dissonance Check out Michel Chion and the idea of the "audio-visual contract" [0] I forget, but it has a more formal definition like source fusing in experimental perceptual psychology. What happens is there is a brief dissonance, but it only lasts for a few milliseconds and then our brains _very_ quickly adjust to align what we see and hear, and crucially what we attribute as the source of sounds. This is a actually not a learned but a low-level adaptation because sound travels slowly compared to light and it reflects (echos) so our brains must be able to re-synchronise effortlessly.
