Sound Engineering Academy, human voice frequency range....harmonics my friend.

Well, I’m not going to disagree, but here’s a fun tidbit to further the discussion:Actually considerably lower: bass E is 79 Hz and there are some basses who sing down to C or even B, which is around 60Hz; OTOH soprano top C is around 1 kHz, and Zerbinetta’s top F# above that is still well below 2 kHz. No human can sing at 4 kHz.
It’s interesting to note (ha) that Dimash Kudaibergen’s vocal range is 6 octaves and 2 semitones, reaching G#7, which is 3322.44Hz. His highest falsetto is D8, which I think is about 4698.64Hz.
🤦♂️ You need to work at it a bit, but you could have a future in stand up comedy...EDIT: Another good question might be who made a proper set of measurements on humans to show that Bybee effects should be taken as purely imaginary? Who took a proper set of measurements on John Curl to show he was lying when he said Bybees can affect sound?
The fact that JC is or is not lying is irrelevant to whether Bybees have or have not any effect.Who took a proper set of measurements on John Curl to show he was lying when he said Bybees can affect sound?
For some reason threads like this one always bring to mind the wars between Lilliput and Blefuscu. 😊
They opened up a small hidden chamber in a hardwood Mpingo disc resonator and found a….. tiny quartz crystal. Yikes!! What does that mean? It means someone was clever enough to put one in there. Open up a WA Quantum Chip and what do you find? Nothing. They opened up an Intelligent Chip and examined it with an electron microscope, lo and behold there was nothing! OMG

At the risk of opening another can of worms, the bybee is a 0.025ohm 5% resistor. Nothing more, nothing less.
But I guess most people already found this info on the net:

Edit: there's a coil around that resistor too, perhaps to filter out the highs.
At least at Pacific, one can read the datasheets, not so when transformed into bybees.

He was excoriated and reviled on this forum for honestly speaking the truth. People here tried to ruin his reputation. All without any measuring anything. Just jumping to conclusions. It was wrongful.The fact that JC is or is not lying is irrelevant to whether Bybees have or have not any effect.
I looked at the pics where you linked. There was more inside than a resistor. IIUC they have a hollow cylinder with some kind of coating that's cooked on. Some may also have a small button-cell battery. There may be a resistor too. What are the excess noise properties of that particular resistor, anyone measure it? What about a fully intact assembly? Also, didn't Scott Wurcer take one apart and find more than a resistor?At the risk of opening another can of worms, the bybee is a 0.025ohm 5% resistor. Nothing more, nothing less.
You are practicing for that stand-up comedy gig, right? 😀All without any measuring anything. Just jumping to conclusions. It was wrongful.
Bybee ‘inventor’ wrote explicitly that any improvement by Bybee is impossible to measure.
Bybee inventor’s explanation of Bybee functional principle clearly show, to anyone reasonable, that he is a fraud.

IMO, anyone reasonable will not claim that a single measurement (SINAD or FFT) is enough to determine how good will some equipment sound. Good measurement results are indication that design goals are fulfilled and careful listening is next step. By a single measurement, exactly the same measuring devices, can sound different. It is the same as that by volume measurement cube and ball can measure the same, jet they are very different. Single measurement can’t determine all relevant properties.If we are going to demand measurements for everything that can be discussed, then we may as well all head over to ASR.
As for the usual subjectivist claims “we don’t know how to measure” right audio circuit properties, it primarily serves snake oil peddlers as a justification for nonsense accompanying their “products”. So, they are very vigilant in repeating that marketing tune.
I will repeat one short fairy tale that subjectivists believe to be true.
One proverbial audiophool bought a good quality audio system and after listening a while and visiting some audio forums, learned that his system can be improved.
First, he bought power conditioner and sound was better. After some burn-in, sound was even better.
Then, he bought premium power cords. Sound was better. After some burn-in time, it was another notch better.
Then, he bought premium interconnection cables, Sound was much better and after some burn-in even more.
Then, he bought premium Quantum Fuses. Oh, what a huge sound upgrade, even more after burn-in.
Then, he bought Synergystic Loudspeaker cables. Sound was much better.
Next, he bought Organic Line cable elevators and sound was better.
Then, he bought cable cooker and improved, for another several notches, all his cables. Sound was much, much better.
Next, he bought ……. and sound was better.
How much can sound be better? Snake oil sellers have an unlimited supply of ‘improvements’, for their bottom line anyway.
And why any of those 'improvements' can't be measured?
Because they don't exist.
I edited my post to add the presence of a 2µH coil, as measured on the forum I mentioned.There was more inside than a resistor
So, it would be easy to calculate what a parallel coil and 0.025 ohm resistance do in series with say, an amplifier's output.

I know people who actually read what I write probably get tired of the broken record repeating, but once more: Bybee's advertising claims were IMHO and in the opinion of John Curl, pure BS. That is happily stipulated. What Bybee claimed in public has no bearing whatsoever on whether not Bybee devices actually do anything or not, and if so what. The symptomatic hallmarks of an EMI/RFI noise generator are suspiciously present. Don't know why people have such a hard time understanding that.Bybee ‘inventor’ wrote explicitly that any improvement by Bybee is impossible to measure.
So when the resistor and coil heat up and or produce some emf across the cooked-on cylinder coating material then what does that do? Do you know that all resistors produce excess noise? How are you factoring everything there into your calculation?I edited my post to add the presence of a 2µH coil, as measured on the forum I mentioned.

No idea if that factor is important for a mil-spec resistor.What are the excess noise properties of that particular resistor
I truly have no idea. (And I won't buy one to try) 🙂So when the resistor and coil heat up the cooked-on coating material then what does that do?
