In contrast, visible light and longer-wavelength electromagnetic radiation, such as infrared, microwaves, and radio waves, consists of photons with too little energy to cause damaging molecular excitation, and thus this radiation is far less hazardous per unit of energy.
Viktor is a Most Viewed Writer in. Physics. If you could somehow make your eardrums sensitive to changes in the electromagnetic field, then yes, you could easily hear radio waves in the 20Hz - 20kHz range. But your eardrums are not sensitive to changes in the electromagnetic field. So regardless of frequency, your ears are completely blind to radio waves. What your eardrums do sense are changes in air pressure, to which they respond mechanically. These changes in air pressure are what we call sound.
