RFI seems to be much more variable in terms of its sound in my experience. Can cause graininess, particularly in the highs if really bad, and/or come through as background hiss or even the sound of radio (as in news/talk/music).
My experience with placment in fields of high EMI is audible hum. Funny thing is it's not always 60 Hz hum, which I expected, but sometimes higher (never lower). Placement of audio components (particularly ones not well shielded) near sources of high EMI also obscures finer details and the all-important sense of air to my ears, even if there is not hum audible when music is playing -- so I'm guessing that the EMI can sometimes be inaudible alone, but affecting the signal as it passes through.
