So why is it you think that RF can't exist at audible frequencies?

What's the definition of "RF" on your planet? :-)

..

Of course, even if these frequencies weren't allocated, this would
not mean that the phenomenon known as "radio" can't happen at those
frequencies. And you can also argue (and I'll agree) that they aren't
the most useful frequencies of the spectrum. But the point is that
RF can exist at audible frequencies.



** However the term "RF" does ***not*** usually refer to such low
frequencies.

The term "RF interference" when used in relation to audio gear refers to
audible signal breakthrough due to nearby transmitters operating on the
broadcast band, short wave bands, the VHF and UHF bands and even microwave
radars.

Interference from signals that are already in the **audio band** is called
just that - audio interference.

The BIG difference is that the latter do not need to be "detected" ( ie
demodulated) to become audible.
