The 432 Hz vs 440 Hz argument is nonsense. Hz is simply vibrations per second and a second is not a nature-defined length of time or some mystical measurement of time, it's an arbitrary length that has no relation to anything.

Some argue that a second is not arbitrary and that it is, in fact, 1/86400 of a day, but days are arbitrary which is why we have leap years - proof that days are not fixed unit of measure.

So, those who make the argument that 432 is a fibonacci number or pythagorean tuning or other arguments are simply arguing for the number, not the sound of A4. So it's a load of nonsense.
