Well...I do time-align my drivers. But digital delay in DSP makes that easy
Sometimes it means that someone peered at it and said it looked OK.
Speed of light is ~ 3e8 m·s^-1. Frequency is 2e4 s^-1. Hence: 3e8 m·s^-1 / 2e4 s^-1 = 3e4 m / 2 = 1.5e4 m = 15000 m
15000 m wavelength may seem a lot, but that wave is really fast.
Well said, my friend!
Just Google it and give it your best shot.
That's in RF. Are we talking RF or sound through air? 20kz sound is less than an inch long in wavelength, 0.675" to be exact or 17.15mm.
Yes, we’re talking about electrical signals here.
Ok, got it! Indeed electrons move awfully fast through a conductor.
Surprisingly slowly (at least I was surprised when I first encountered analysis of electron velocity though conductors). EM waves, on the other hand, move at a good fraction of the speed of light.
Reminds my of my sister who liked to back the wall plugs out and drop pennies behind them when we were growing up. Showed me one day and I was like "I don't think that's such a hot idea, Jen." Made a hell of a bang, esp. with the copper plated zinc ones. Really annoyed my parents since after a while most of the wall sockets with things plugged into them eventually ended up with skid marks on the socket covers and walls. Ah, the joys of youth. Provided you don't die along the way, you end up with lots of odd and unusual memories...
There was a paring knife in our kitchen junk drawer when I was growing up with a circular chunk taken out of it.
So long as the astrophysicist writes in his area of expertise, then he is a credible source of information in that field. As soon as he steps out of that field, then he's no better than the rest of us chickens, bedawk!No, he is just neglecting the significance of all he finds for audio, omitting things, etc etc Sure he is a great astrophysicist. He's just having fun, I was serious about it.
To be honest, I wouldn’t trust any papers he writes in his field expertise either. We don’t know how deep his Dunning Kruger goes. He’s an audio sharlatan, why would that be different in other fields?
I have to endorse @voodooless ^^ and others on that. Scientists, true ones, are very humble and have a deep respect for the truth (for what can be proven) in all academic fields and specially outside their own.
