Svar till: TX frequenciy audible

[Roland]

Is not possible to directly hear electromagnetic Waves. What the Humans (and Animals) ear is able to hear are longitudinal (pressure) waves.
These Sound Waves are mechanical nature and need a Media (Air, Water,…) to propagate. Electromagnetic Waves do not need a Media for Propagation
(Vacuum!) The low Frequency does not cahnge this behaviour.
Example:
If this would be possible you could hear the 50Hz of the electric power Grid as well. When you hear a Transformer sounding it is the mechanical
resonance induced by currents to the Transformers core.

Kind regards,
