Attention Scientists, Engineers and Na-s


Isn't it funny how timing works. With all the different discussions on proving this, show me fact on that and the psycho acoustical potential of the other thing an article comes along with the same topics and some REAL potential answers. I received my newest copy of "The Audiophile Voice" Vol.7, Issue1 today and on page 16 is an article written by David Blair and Bill Eisen titled "In The Matter Of Noise". The article focuses on disturbance noise but has some reference to thermal noise, low frequency noise and shot noise, and our ability to measure these noises with the equipment of today. We have measured noise as low as 6x10 to the power of -5, or approximately a few cycles per day. We have also found through laboratory testing that the human brain is stimulated with frequencies from just above 0Hz to just below 50kHz. U.S. Department of Defense documents also show studies of low frequency activity below measurable levels and there various affects.
The article then begins to talk about out of band (hearing) noise and in band noise produced by our electronic equipment and the potential of these noises effecting our sound system. The assumptions are that "disturbance noises rob our systems of dynamics, low-level information, tonal purity and stage depth". These effects are for the most part overlooked and misunderstood by the scientific communities. They say they think that our speakers being hit with "massive quantities of R.F.I. are affected" A very good quote referring to power filters was "Effective noise control imposes no sonic tradeoffs or downside." How often have the discussions here on Audiogon focused on what they are doing? A very interesting comment was that Teflon is capable of carrying 40-Kilovolts static charge, and the industry is touting this as a great insulator for audio signals, that's scarey!
Now I bring this to light because I believe the view of the "Scientists and Engineers" here on Audiogon is so narrow that they are failing to see the exciting challenges in front of them. If all these noises do exist, which they do, and they can be transmitted and received through our systems, isn't possible, just maybe feasible that the insulation of our wires, the casing of our dedicated lines the size and shape of the conductor could, just maybe effect the sound? Isn't it even possible that forces set off by electrical components could be interfering in some so far unmeasured and inaudible way affecting the sound. Do you all test within the full spectrum of 0Hz to 50Khz for every possible situation? Or is it possible, just ever so small of a chance that you are overlooking a whole new science yet unexplored. Doesn't that, even slightly excite your little scientific fossils?
Man if I was younger, healthier and wanted a challenge. This is a career if you'd just climb out from behind you oscilloscopes and spectrum analyzer and see the world is indeed still spinning, and yes, it is 2001. Remember how 30 years ago 2001 was going to be so exciting. What the hell have the Scientist, Engineers and Na-sayers who tote there stuff here on Audiogon done for the advancement of science. Anyone, have any of you really broken through! J.D.

A true scientist would retain an open mind as has been pointed out here. But the scientific method can become a trap, or at least a constraint on what might be achieved.. History has taught scientists that failing to rigorously prove new theories can lead to decades of wasted endeavour, and so the inherent scepticism of the scientific method has been learnt the hard way. But having said that, it can be argued that the scientific method has closed medical minds to many potentially beneficial ways of treating people other than getting out the knife or prescribing pills (sorry to you doctors for being so harsh - I know I should qualify that statement, but space does not really permit). Therefore many scientists have found there is value in a little bit of a walk on the wild side every now and then, in order to create new possibilities. The value of doing this and how to ensure it does not just result in wasted time on fanciful notions is a debate in the scientific community and one that each scientist needs to take a view on. So there is a tricky balance for any scientist between wasting time on silly ideas and failing to make progress because of too much scepticism. I think the scientists that cause my blood to boil however are those that simply made a career choice mistake and should have become accountants. The world is made up of all types, and accountancy is one of those areas where ambiguity or a lack of rules that cover every eventuality is not tolerated (lest it allow an unscrupulous management to tell lies), and therefore tends to attract people that feel more comfortable in a profession where there is an unequivocal answer to every problem (apologies to the accountants I have now offended). Accountancy is a very particular type of science where a fundamental theory is at its foundation, and all the detailed rules are deduced from this. (Before I get shot down - I know that this is a simplification by the way as I have studied the history of accountancy in some detail). But the scientists that make my blood boil are those that approach audio in that same way - with the assumption that existing electrical theory is a unified theory of audio and that all there is to learn is deductive from that. Even if they are right, they are making a huge and unjustified assumption, and therefore hardly earn the right to the scientific high-ground - which they so commonly claim on these forums. I just want to emphasise that I do not accuse all scientists of this fault at all.
Stevemj - your claim that power cords cannot make a difference strikes me as exposing the fact you have not tried listening for yourself with an open mind. There will be many here that have tried power cables (on decent systems and on suitable music) and found very significant differences. Of course, when I say significant, I mean musically significant, whereas I suspect you would assume I was claiming something else. But then again your frame of reference does not appear to be music at all. As it happens, I organised and participated in a blind test where three of us were subjected to four different power cables being substituted by a fourth person according to sequences that had no discernible pattern - I wish I had the sequence available to me now to show you. I happened to know the sound of each of these cables very well, and had refreshed my memory of them on the music sample we were using immediately before the test. Another participant was a "golden ears" who was given no prior familiarity, except in the lead-in to the test. The third was a novice. At first we just used two cables, the best of them and the stock cord. Then we used all four, for a real test of our hearing ability. Not surprisingly to me all three of us could reliably pick the cables in the two cable comparison (I was 100%, so was Golden Ears, and the novice was 69%). When we mixed four up, it was much harder. I got it wrong twice, Golden Ears had no trouble distinguishing the two cables used in the first experiment but mixed up the other two a lot of the time, and the novice got terribly confused and worn out by the whole thing. You will have to appreciate that I am going from memory on something we did a year or so ago, and which I only did to satisfy my curiosity. This was my one and only attempt at a double blind test and it didn't tell me anything I didn't already know. Now you will ask me for documentary proof. I suppose I could get affidavits from the four people involved if you really need it.
