Why does the air hum/buzz around the WWV transmitter site?

I can't find the video but there were some ham radio people that recorded a tour of the Colorado  5.0MHz site.

When they stood under the huge antenna the air made a really strange sound not just a hum like you might expect but another sound I can't really describe. Do the antenna wires vibrate at some harmonic? It didn't sound like electricity either. Strange.

We shall put effort into answering your question but you can't even find video you have question about? - Try harder.

It's high frequency electric field. Reason why sound differs from high voltage (AC) electric power transmission line - it's high frequency.

High power transmitter antennas usually buzz.  It's not just WWV.

  • I like vacuum tubes. Electrons exist, holes don't.

Given the power of the WWV transmission it's possible that the RF could be interfering with the audio circuits in the camera.

It may be caused by corona?

A friend lived near a transmitter. His electric stove would play music.
