As a kid, I could actually hear some EM quite distinctly. It was only the stronger pulse-like stuff, like arcing transformer a hundred meters away, or lightning strikes within about 2km. I can still hear lightning strikes that are fairly close as a faint crack in my head, a second or so before the thunder, but this ability seem to be diminishing as I age.
Of course, there is no frickin way anybody can feel 100mW of 2.4GHz radiation from any distance, and not feel 1kW (although shielded, but leaking a lot more than 100mW) microwave oven.
