You are late to the many posts on this forum during most of last year here on the dodgy subject of what is the audio signal and how does electricity in audio circuits work?The short answer is yes, your ears hear the *effect* of Radio Frequency interference. Obviously we don't hear RF directly, that would be absurd. They aren't acoustic waves.
The reason is because radio frequencies are *electromagnetic waves*. And external electromagnetic waves produce noise and distortion in audio signals because audio signals are themselves, you guessed it, electromagnetic in nature. Poynting vector with E and B fields.
Analogous to the deleterious effects of RF on our hearing is the effect of Very Low Frequency seismic type vibration, also outside nominal 20-20k Hz audio frequency bandwidth. Seismic type vibration is around 1 Hz - 20 Hz approximately.
The ball is in your court.
