Why would it matter. As I said:
"But aside from grudge matches, we must not lose track of the fact that the hearing abilities of just one person has very little logical value to anybody other than to him."
Does this statement need some kind of paraphrase or clarification?
What is opaque about it?
Here's reality. Other people's false protestations to the contrary I've been working hard since the mid-1970s to promote highly reliable listening tests that detect both false positives and false negatives:
In 1977 Arnold B. Krueger and Bern Muller, both members of the Southeastern Michigan Woofer and Tweeter Marching Society (SMWTMS), invented the ABX Double Blind Comparator System in order to settle a debate if differences between well constructed and level matched amplifiers are audible, Muller being pro and Krueger being against the possibility. On May 7, 1977 SMWTMS organized the first three audio double blind listening tests using Krueger's and Muller's ABX Comparator. Consequent to the meeting a company that will manufacture and sell the ABX Comparators was formed under the name ABX Corporation. Later David Clark, member of the Audio Engineering Society (AES), will continue to refine, promote and market the ABX Comparator.
On September 22, 1999 Krueger launched a website fully dedicated to educating about ABX testing with included software applications for download.
The PCABX web site can still be inspected on the Wayback machine, and there one will find a permanent record of an elaborate listener training facility that clearly exposes people who can't hear differences.
Not mentioned above are the vigorous and highly regarded efforts of David Clark who while working with his employee Mark Ziemba, devised a training product he calls Listening Technology in the early 1990s. I contributed nothing direct to this effort, none at all. It is not widely known or documented because it is a proprietary product that was sold somewhat privately for healthy fees, in essence a trade secret. Clark himself describes it below:
"For over 20 years David Clark has been training the automotive industry on how to evaluate audio systems. His method, Listening Technology, has become the standard for many auto-makers in North America and Europe. This objective technique utilizes a reference system, standard program material and many measures to minimize bias. Clients include global vehicle manufacturers, audio system suppliers, loudspeaker manufacturers and electronics suppliers."
To the best of my knowledge LT preceeds the well-known MPEG work that was described in the JAES by James Johnston, and involved some of the same musical passages. I don't know how much JJ knew about LT then or now.
