a speaker and amplifier company that does not sell wire.....yet they spend time and $ to listen and mark the various spools......

What do we hear when we change the direction of a wire?
Douglas Self wrote a devastating article about audio anomalies back in 1988. With all the necessary knowledge and measuring tools, he did not detect any supposedly audible changes in the electrical signal. Self and his colleagues were sure that they had proved the absence of anomalies in audio, but over the past 30 years, audio anomalies have not disappeared anywhere, at the same time the authority of science in the field of audio has increasingly become questioned. It's hard to believe, but science still cannot clearly answer the question of what electricity is and what sound is! (see article by A.J.Essien).
For your information: to make sure that no potentially audible changes in the electrical signal occur when we apply any "audio magic" to our gear, no super equipment is needed. The smallest step-change in amplitude that can be detected by ear is about 0.3dB for a pure tone. In more realistic situations it is 0.5 to 1.0dB'". This is about a 10% change. (Harris J.D.). At medium volume, the voltage amplitude at the output of the amplifier is approximately 10 volts, which means that the smallest audible difference in sound will be noticeable when the output voltage changes to 1 volt. Such an error is impossible not to notice even using a conventional voltmeter, but Self and his colleagues performed much more accurate measurements, including ones made directly on the music signal using Baxandall subtraction technique - they found no error even at this highest level.
As a result, we are faced with an apparently unsolvable problem: those of us who do not hear the sound of wires, relying on the authority of scientists, claim that audio anomalies are BS. However, people who confidently perceive this component of sound are forced to make another, the only possible conclusion in this situation: the electrical and acoustic signals contain some additional signal(s) that are still unknown to science, and which we perceive with a certain sixth sense.
If there are no electrical changes in the signal, then there are no acoustic changes, respectively, hearing does not participate in the perception of anomalies. What other options can there be?
Regards.

Despite
not science still cannot clearly answer the question of what electricity is and what sound is (RE: "science still cannot clearly answer the question of what electricity is and what sound is!), I must point out that you must mean, "Science, as determined by the what we choose to measure and by what equipment is available to us, might not always correlate with sounds we perceive". |
djones513,824 posts This is very strange to me. Are you applying to be invited to a measurement session? Self is an authoritative audio engineer, he wrote a detailed description of the experiments conducted, gave data from psychoacoustics, there are links, if you want, you can check everything. Isn't all this enough to be shure? The question is rhetorical, you don't have to answer. I want to thank you and apologize for bothering you so much. Regards |

Isn't all this enough to be shure?Self said audible differences in the direction of wire is nonsense. If there were any measurable differences it was irrelevant. Since he is an authoritated audio engineer and I'm not I'll defer to his opinion. |
Maybe someone already explained this, but I simply didn’t have the time to look through the whole thread. Due to manufacturing tolerances, a cable isn’t electrically the same from both directions.Very astute remarks... In my precedent posts i insisted with Essien and Ansermet about the specific irreductible ability of perceptive consciousness versus measure technological pretense to explain the world of meaning and phenomenan ONLY by some chosen dimensions and parameters... Now i will add a more theoretical physical background inspired by the idea of a great Russian scientist who wrote about TIME and energy and the anisotropy of the cosmos... For Nokolai Kozyrev the DIRECTION in the universe between right and left and between cause to effect or between effect to cause are not EQUAL...and the diffreence is even measurable in his many experiments... Here is the link to the article... http://www.univer.omsk.su/omsk/Sci/Kozyrev/paper1a.txt He is not a crackpot either if you look to WIKI... I say that for the possible presence of a sunday "scientism" skeptic club member lost in this thread... Then if the direction between cause and effect or effect to cause are different qualitatively and quantitatively and even measurable for Kozyrev, perhaps the human ears can perceive some microscopic effect "percolating" through smaller scale to them...Even if our actual instrument dont measure them... Then wires can exhibit this difference in quality quantitatively between the origin and the end of a complete circuit .... It is a speculation from me with Kozyrev for sure but..... There is more under the sky than meet the ears or the microphone itself.... This does not preclude the necessity for a test of perception between cables or wire.... «Creating the cosmos is a only way for God to test his own hearing»-Groucho Marx 🤓 |
