The human ear cannot hear radio waves because they are electromagnetic waves with frequencies typically ranging from about 30 kHz to 300 GHz, which are far below the audible range for humans (20 Hz to 20 kHz). While radio waves can be detected by radio receivers, the ear is designed to respond only to sound waves, which are mechanical vibrations transmitted through air or other media. Therefore, the fact that we require a radio receiver to convert radio waves into audible sound supports the conclusion that the ear cannot directly hear radio waves.
