Just because a note is below the range of a piano keyboard or even human hearing doesn't mean it can't exist.

True, but one shouldn't call this "sound".

Sound wave would probably be more appropriate.

This is really for everyone not just Izzy Dunne :-) Science catching up with the Bible? Not bloody likely, ever! :-) The Bible is a very old and unchanging compendium of opinion. It is inflexible and fixed as surely as a photograph from the American Civil War is fixed or an Egyptian hieroglyph is fixed upon the wall of an ancient tomb. The Bible is an archeological work. Those who choose to believe the Bible is more than ancient speculation and wishful thinking, will never change their opinion because for them it is all a matter of faith in that arcane philosophical position.

Science on the other hand is dynamic, flexible, moving, in a neverending process of change as new information is uncovered. I do not say 'discovered', because the information is all out there in the Universe, regardless of whether or not we are aware of it.

Black holes were still only theoretical less then 10 years ago, now they are confirmed as real and are known to be the central feature of most if not all galaxies. They are also found in locations other then galacic centers. A black hole 'singing' a continuous B-flat monotone in any octave is certainly a new wrinkle in the cosmological fabric, to be sure, but how that relates to anything Biblical is a deeper mystery to me than the phenomenon itself :-)

Actually I think using a sound scale is the best way to describe how low the frequency is. If you were to describe it in hertz, it would be a very very tiny fraction of 1 hz, which most people including me, would probably just gloss over.

Infra"C"?

From a radiation survey course I took so long ago, people were concened about the effects of ultrasound on human tissue, milliwatts per square centimeter, iirc.

Not that I'm personally worried, but watt is the quantification of power for this wave and its effects on man-in-the-Moon-marigolds?

Nanowatts per square AU? Square lightyear?
