This kind of over dramatizing is tiresome. "Demonic chords" (what's a demonic chord, anyway? Are bees buzzing in a tritone? Are bee hives playing chords?), talking about it sounding like a 1920's vampire movie, etc. Sure makes it sound like nothing in the world could be more creepy.

Then you go and watch a video demonstrating this effect, and it's more like the humming/buzzing sound from the hive is... slower. That's it. It's just slower, lower frequency.
