“Tuned to 440Hz” is a nonsensical statement to anyone who did music or physics for a second

If the instrument is tuned to F it means that notes are arranged in the Fmajor scale. Every note has it’s own frequency. If all that would come out of the radio would be 440Hz it would be literally one tone.

I’m not saying that 432Hz doesn’t have all those properties. The “healing music” stuff has that exactly one tone in the background throughout.
