The radio frequency at a wavelength on the order of 10mm is around 30GHz. While harmonics at a few multiples of 20kHz exist, and a good case can be made for their influence on lower (audible) (in air) frequencies, thirty billion seems a bit of a stretch.
>>>>>To be fair I said effects were measured for the one inch tiny bowls. That’s why I asked what diameter the SR bowls are.
Then too we have the problem of knowing they work equally as well both directly on electronics as well as on the outside case of components. They also work on a tone arm- and not on the cartridge which would be electrical but on the tone arm rest far from any electromagnetic field.
>>>>>The acoustic waves and the *electromagnetic waves* are everywhere. Since I have not had the pleasure of using the SR products I can’t say yeah or nay.
A lot of this is conjecture. But one thing we know for certain, electromagnetic fields attenuate according to the inverse square law. Another thing we can know for certain, we can’t have it both ways. Either its electromagnetic, therefore attenuates with distance, or its not. It does not attenuate with distance. Therefore its not electromagnetic.
>>>>>But we’re not discussing *electromagnetic fields*. We’re discussing *electromagnetic waves* - I.e., radio frequency waves. So forget about the inverse square law. Electromagnetic waves travel at speed of light.
Also if its electromagnetic then why would it be so necessary that they be securely fastened that SR includes both white tack and adhesive?
>>>>I don’t say it was strictly electromagnetic in nature or even that SR claims it is. I was making an observation based on the similar products from other manufacturers. Like Franck Tchang.
Electromagnetic radiation goes right through clothing. They would work even in your pocket. (Or in the box!) Also in order to work electromagnetically they would need to be, you know, magnetic. Ferrous.
>>>>That’s actually incorrect. They don’t have to be magnetic. Franck Tchang are silver or gold or platinum. Not ferrous. As I already noted effects were measured up over 2 GHz. If electromagnetic waves were magnetic you would be able to bend light with magnets. Which you can’t.
At least a little. But they’re not. Because then the last place you would ever want to use one is stuck right next to the delicate electromagnetic field of the phono cartridge. Which is exactly where they tell you to stick them!
>>>It’s not an electromagnetic field, it’s a magnetic field, around the cartridge produced by a moving inductor. Or, if it’s a moving magnet an electric field.
One way to figure things out, rule out everything it cannot be, it must be what you’re left with. Electromagnetic dog don’t hunt.
>>>>Nice try. Better luck next time.
