I used an example of single note music in order to get away from the pure tone problem, and also to have overtones and harmonics. So it would be music, but simple enough that anyone with good hearing could hear a difference between the signals, if such a difference is possible.
This isn't a complicated problem. Determining if a signal is different is possible. Determining if the difference is audible is possible. Determining if it is "better" is not.
If scientific analysis and measurements of the frequencies isn't good enough, then the switched source demonstration would make it OBVIOUS if a difference can be heard.
So far it seems to be about a person being able to tell, not about science. If there is no difference in the signal, then any other test is just a waste of time, and this is showmanship, bluster or something. If there IS a difference, then you test to see if it can be heard, by people with good hearing.
The claim is nobody can HEAR a difference between the cables, that the frequencies claimed to be better are not detectable by human hearing. If there is a difference, and it can be heard, by anyone, then different cables are different.
Trying to establish that one is better than the other is a matter of opinion. Establishing that the difference is possible to hear, is science.
I really don't understand why this is hard to grasp. Maybe it is a lifetime of audio work. I understand how audio works, I know how equipment works, I know hot to conduct a scientific experiment, to measure stuff, to show anyone what a different signal looks like. It is easy to do.
I explained a simple way to demonstrate being able to detect an audible difference. So that the results satisfy the MDC rules.
1. This is the primary and most important of these rules: Applicant must state clearly in advance, and applicant and JREF will agree upon, what powers and/or abilities will be demonstrated, the limits of the proposed demonstration (so far as time, location and other variables are concerned) and what will constitute both a positive and a negative result.
Saying when the signals are being switched constitutes a positive result, not being able to say, or saying incorrectly, constitutes a failure.
2. Only an actual performance of the stated nature and scope, within the agreed-upon limits, will be accepted.
You play the recording, nobody at the time knows when it is a steady source, or when it is being switched. If you can't hear a difference, that is a negative result. If you can hear a difference, that is a positive result. At the end of the performance, you check with an electronic analysis of the recording to verify. But the beauty of a scientific test, as I described, is that the results are self evident. Anybody with good hearing can tell when it is a constant source, or when it is being switched back and forth. No need for any complicated protocols.
15. EVERY APPLICANT MUST AGREE UPON WHAT WILL CONSTITUTE A CONCLUSION THAT, ON THE OCCASION OF THE PRELIMINARY OR THE FORMAL TEST, HE OR SHE DID OR DID NOT DEMONSTRATE THE CLAIMED ABILITY OR POWER.
A no brainer. You either hear it, or you don't. No complicated switching of cables or sources or anything required. Zero wiggle room for either side. It also has the benefit of being a test that both sides can do without the other present. Anybody can do it. No questions about the results, either way.
What is wrong with that? Nobody can claim trickery or deception or reasons for failure or problems with equipment or setting or anything. By making it a matter of science, the same test can be done over and over, with no doubt as to the results.
How many other "paranormal" events or properties have that advantage?
I suspect one or both sides at this point are hoping to avoid such a simple yet scientific way to test the "claim". If I was going after a million dollars, I would have already done the test, before discussing protocol. Pear stands to benefit from doing the test, if it shows them in a good light, even if there is no challenge.
Randi stands to benefit if it shows no difference is audible, even if Pear rejects the challenge.
Somebody has to win.
