The Arabs were almost right on the money when they calculated the

my argument still holds that simply not being able to measure something is a
poor argument for something not being there.

I'll just sum up my previous long-winded article again he

In the field of audio, we ARE able to measure everything in a signal
that's audible, and can measure all of it to levels far below audibility.
That's why if we don't measure a deviation in the signal, we can say
with confidence that there's no audible difference.
