Simply, let me see what does observation mean? Watching, listening, measuring, ie. using ones senses. What does scientific mean? Being as objective, seeking scientifically transmissible data, measuring with valid instrumentation, ie. being as open to what one is focusing on as possible.
Great.
So now where does the "scientific" part factor in here with regard to directional fuses and your claim of "scientific observation"?
If all you're doing is listening, then by definition you're not being objective. Listening on its own is a decidedly subjective matter.
I repeat my earlier statement. You are close-minded and apparently fearful that you will hear something, although the nocebo complex, hearing nothing because you believe you won't may affect you.
Not at all.
You're not getting it.
Even if I tried it and did perceive a difference (please note I did not say "hear"), it would prove nothing one way or the other.
Why?
Because I'm a human being. And like all other human beings, I'm just as susceptible to perceiving differences even when none exist in any actual physical sense.
And until that ambiguity can be adequately controlled for (and it can't be controlled for by way of vanity and ego), my trying it for myself is pointless.
