I actually never really tested it. I suppose this is something that may be experienced when listening longer time to a piece of music, or over a longer period of time listing too many pieces of music. I can imagine the brains get adjusted. But such adjustment may not be good for a optimal experience, ie the 432 Hz may give a better experience over the 440 Hz when the brains get adjusted to the 432 Hz.

Ah, good point ;)
