I can't! It's all hearsay. Muhaha.fearfaoin wrote: Can you cite a source on that?
But seriously, as you said: all electronics ring or hum at that frequency, in the US. Not only 60 Hz. There is some higher ringing produced by TV's, Fridges, Computers. All at Bb in some octave. It's really annoying. I've heard there are scientific, peer-reviewed, legit studies on this "Bb resonant frequency of the universe" thing, but I haven't actually seen any.
Also, my ears constantly RING at Bb. A very, very high Bb. This is what they call "tinnitus." The ringing is aggravated by certain electronic devices, especially certain kinds of lights with triggers. If there is a flashing light nearby, I can often close my ears and eyes and hear the flashing as the Bb frequency in my ears pulses slightly louder and softer--or it seems to take on different overtones or something. I have to be within a certain distance of the light (more likely the electronics) for this to happen, but I do not have to see the light. It does not need to be flashing at me, I could be on the other side of it, some fifty feet away, depending on the power of the device. VERY odd. I wonder if this has something to do with the auditory nerves receiving and processing certain kinds of electronic interference, since nerves carry electrical impulses.
Right. Er, where were we? Low F whistles? Yes, yes. Special pipes they are.
