Krivium really wasn’t paying attention to the Schumann frequency discussion. That’s the whole point - it’s not physical. Unless maybe you think you’re getting a scalp massage.
There is a white paper.
They go to extremes with VERY black paint to minimize any light reflection from inside the mechanism.

Geoff, i was paying attention to the discussion, even asked you which sub you use to produce the tone in question but didn't had an answer.
Another point got me more than sceptical: as an engineer performing recording, mixing and mastering duty, we have the habits to clean the low end by high passing it.
I regularly had to clean up takes done into places where A/C produce such very low tone. We do it on purpose but maybe we fool ourselves about it?
Dave, If you want really lower secondary emmision within a mechanism you can do it by other means than paint: if metal parts there is some surface treatments to make reflectivity practically null availlable ( used in telescopes, industrial and military equipments) and i think i remember being told plastic parts can be treated as such ( different process though).

I am sure. But great strides have been made recently with new black (and white) paint/coatings in the last few years.

We live in the physical world. Anything that's real must therefore be physical. That's the philosophical justification for why physical matters.
The practical justification is that if you deny the physical world you are putting yourself in the crosshairs of scientists and engineers. Don't be surprised if they say things about you that makes you feel like you are being hated. Your denial of the physical makes you look boldly dishonest to them. They see you as one of the bad guys, the snake oil selling rip-off artists. When that happens, seems like you don't like it. Yet by now you should have enough experience to know what will happen. You go ahead and poke the tiger anyway. Probably not the wisest way forward.
OTOH, if you can express your observations in plausible physical terms meeting the criteria for a scientific hypothesis then you have a chance of being taken more seriously. Don't know if you can see that or not.

As I already mentioned colors, including black, do not absorb light in the CD laser spectrum, except for the visible red portion which is there only as a safety precaution. 75% of the CD laser light is near infrared, 700 nm to about 850 nm. Turquoise green is the complementary color of red, that’s what the hoopla about Green Pen was all about. It absorbed some of the laser light. As I just mentioned a little while ago using black around the outer edge of the disc hurts the sound. Does that surprise you? Best to use purple or green. But black is very good on the inner edge. Go figure. Some Italian company uses turquoise on the tray, which is what I’ve been using for twenty years, until now. I have the ability to absorb all light, visible and invisible.

In my silliness, I tried to think rationally.
Regarding CD players laser beam, it emits at Near Infra Red (NIR).
At these wavelengths (around 780nm), black color behaves very close to how it behaves with visible light. It does not reflect NIR but absorbs it.
This is what I had thought but I hadn’t checked the CD edge treatment with an IR camera. Mea culpa.

Mark, what I said was some things that affect the sound are not physical. You know, like Herr Schumann’s wave. Here is a question for you, a Google scientist. What is the function or importance of the Schumann wave for humans? And Alpha waves, Theta waves. One more question, do you think the mind is physical? How about the subconscious mind?
The Schumann tone 7.83 Hz I have playing now whilst listening to music on headphones is not audible, nor would it be even if it was completely silent on the room. Yet, the sound is glorious, full, open, extended, dynamic.
One last question, what do you think the meaning of this is,
The universe is locally not real. Hint Nobel prize in physics last year for proving that statement is true. Live and learn, right?

It is known that low pitched tones can affect brain waves and temporarily alter our heart rate. Every competent DJ understands that. Crappy sound alert.

That's exactly how I feel about science deniers. And I live in a country where science denial is considered patriotic.
And every supposed “sound professional” will insist that anything below 40 Hz is an absolutely unnecessary expense and MUST be dispensed with.
Mierde de Toro. The bigger the speakers the bigger the sound (I heard that in hip hop somewhere ages ago).
Markw4, name one (repeat one) audio manufacturer who uses ANY of those near infrared absorbers. Betcha can’t.
Schumann resonance is real: https://en.wikipedia.org/wiki/Schumann_resonances There may or may not sometimes be a Schumann wave that launches off into space with any appreciable energy.
Yes to both. Also its clear if you would read some of the links that I posted that the human brain is sensitive to very low frequencies. Whether or not that has any relation to Schumann resonance is, so far as I know, unknown at this point. However, we do know that lunar cycles modulate gravity on the Earth, and that such variations can correlate with biological functions. Maybe when our ancient ancestors were single celled organisms they were sensitive to Schumann resonance effects. If so, maybe we have inherited some some of that sensitivity. Don't know. What we do know is that 7-8Hz stimulation of the brain can have measurable mental effects. So, if you use some method to stimulate that frequency in your brain, maybe it could make music perceived as better sounding.
Doesn't have to be audible. It just has to get into your brain somehow. Pulsed EM radiation could do it. Beat notes you can't hear could do it. If your brain responds in a similar way to both, then it doesn't matter if you hear it. Hearing is just a perception. You can't perceive all the ionizing and nonionizing radiation passing through your body all the time. So what? Its still there and doing whatever it does.
Maybe if you take a THC pill the same thing will happen. You can't hear the THC that gets into your brain, but the music may still sound better as you perceive it due to the presence of the THC.
It has to do with quantum mechanical and similar stuff. The words 'real' and 'local' have particular meaning to physicists in that case. Its not the same meaning as the lay definitions of those terms. If you really want to know more about the physics, there is some brief discussion/explanation at: https://physics.stackexchange.com/q...lying-idea-behind-this-2022-nobel-prize-story
That said, you may need to take special care to try to understand the technical nature of the terms if you want to get anything meaningful out of it. OTOH, if you just try to re-use the words in your own way, most likely all of the original meaning will be lost.
so, you believe the mind is the same thing as the brain? And I like the way you skirted around answering my question, what is the meaning of The Universe is locally not real. And what do you believe very low frequencies are doing, massaging the scalp? Quick, Google is your friend. 🙂
