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?

I have a fairly inexpensive but sturdy Hamilton Beach that I have had for several years. I checked the temperature with my candy thermometer and it is accurate. It had one feature that was important to me.  When you set it to a temperature other than boiling, it will hold the temperature for 30 minutes. I have a habit of turning on the kettle then forgetting. This gives me 30 minutes to remember.  I would just pick whatever has the best ratings at Amazon and go with that.  This one only has 6 settings which is probably enough, but it has good ratings. Some of them I noticed are prone to leaking. When I buy off Amazon, I sum up the 1, 2 and 3 star percentages and look for low numbers. I find this more important than the average. It avoids duds.

Tu as l' air de beaux esprit, mon ami!
J' espere que tu vas bien.





Merci très bien même...

J’aime la complicité entre amis ici et j’écoute de la musique tout en lisant un article d’un auteur dont j’attend le livre demain, sur l’acoustique, qui me semble une révélation déjà...

Merci pour ta sollicitude mon ami....

I will imitate you now....

"I drink black tea to which i add a bit of orange marmelade..."
Now, that is an interesting approach from whichever direction.

Is it ok with decaffeinated tea?

Why not.... But i enjoy it only with black tea and very little amount of orange marmelade, if too much you will spoil the tea.... Only a bit on a teaspoon...You must not taste the orange but only guess it is there....
