Their design cuts the most shrill and annoying frequencies by about 12 decibels, which all but removes them, making them 94% quieter.
We agree that the -12dB is what’s important for human hearing … Now, you may agree that the 94% reduction is what counts regarding engineering // fabrication // design.
I agree that it is good to know the proper name of things and I appreciate your post because of that and because of the schematic which I found intriguing.
…but here my comment was a attempt to put forward the humorous similarity to country rock music. … i did notice over time I’m not efficient at formulating jokes in ways that readers will get.
Likewise, in 1995 M$ made WinRAR. it took the place of a much better product that was PKZip which existed since 1989. Since then I always see crooked things in each of their products and predatory commercial moves.
from your link : “WinRAR is a Windows-only program.”
… you are right that it was created by someone else in an independent company but then distributed by M$ … the important part for me is that it came after PKZip and took its place, and is worse.

No, not the same … in your paragraph you describe an increase of the frequency at a level human hearing do not perceive while the other made cancellation of a given frequency using phase shifting and recombination.

a.i. functions differently than human minds and so at times it appears very intelligent and a time very stupid … in fact it is simply different.
Let’s make the best of our differences.
a bit of the abstract:… By integrating efficient bidirectional quantum frequency conversion of photonic communication qubits to telecommunication frequencies (1,350 nm), we demonstrate the entanglement of two nuclear spin memories through 40 km spools of low-loss fibre and a 35-km long fibre loop deployed in the Boston area urban environment, representing an enabling step towards practical quantum repeaters and large-scale quantum networks. …

Hi @TCB13,
i will try to meet you half way. Clearly you disagree and might have been triggered by my first comment above which was bold in a sense.
i will agree with you that America also, as a country, has done some bad, terrible things abroad and so did many other countries … but please tell me this : Do you at least put some blame on russia for the war in Ukraine ?

i blocked that “blahaj” long ago. it is a shit hole. if you continue to visit it you will get it.
Still, to be mindfull i read from your link :
x says - - tldr :
if woman alone in a forest : is she better to encounter a bear or a man ?
x says...Okay very basically this whole thing started with a hypothetical posed to a bunch of women about which they would rather run into while alone in the woods; A random man, or a bear. A lot of women chose the bear. Reasons varied from “The worst the bear will do is kill me,” to “At least I know the bear wants to kill me,” with a general theme seeming to be that whatever tangible threat the bear posed was preferable to the uncertainty of wondering whether or not a random man would assault them. The poster’s stated goal with the hypothetical was to get men to think about why the women were choosing the bear. Instead a lot of guys took it as a personal attack, like they were being punished for the actions of other men. Many started attacking the question, insisting that bears are way more dangerous than virtually any man. This led to a lot of dismissive responses of the criticism like “This is why women choose the bear,” or talking about women’s safety being more important than men’s feelings. I’m simplifying a lot but that’s the basic gist of it.

op answer to x@spujb@lemmy.cafe ((OP)) Thank you for the detailed summary. To add the final unfortunate details, there was a recent discussion on Lemmy where women were sharing their reasons for choosing bear, which involved sharing personal stories of SA. Unfortunately, many men responded in a toxic manner, causing some women to delete their posts or accounts. Very disturbing and this is what inspired me to make this post, as it is quite reminiscent of the Catholic church sweeping SA under the rug.

my opinion :
ideally if a woman had a gun she could kill the bear without any bad consequences … but she could not kill the man without legal risks. So ideally she would be better off encountering a bear … though in some countries there is no problem with encountering a man (most of the time).
