Acoustical feedback energy system

Do you have an experiment to share ?

Oh, read post #1 or https://vixra.org/abs/2012.0066 I'm not taking all this from my imagination only. From what I understood, people don't know what happens when a loudspeaker is hit with an equally-powerful, same-frequency, but opposing soundwave of some phase. It's just not studied at all, probably even looks like a non-sensical system for many. And that was the opportunity: simple experiment, unusual results.


Search for "opposing loudspeakers" on YouTube or Google and you'll get almost nothing.

Dear aleks -You are not conducting  mentioned experiment, but talking nonsense/Absurd for 9 pages now.}

Reedited by Wesley from "aleks language" into  physics in English language:
Two loudspeakers, _{for example : 4 meters apart} and facing each other, play identical sounds of the same frequency
You stand _{(or just taking  measurement)} halfway between them,- _{( the same-frequency, and phase. )}

1.sound waves are  pressure waves. have nothing to do with electromagnetic wave.
2.because of the symmetry, an air-element at the midpoint (P) does not move. This gives a displacement-node at P.     
   P is a pressure-antinode because of the movement of the air around P. The air around P moves like this:
→P← during a compression (increasing pressure at P)
←P→ during an expansion (reducing pressure at P)
but the air at P remains stationary.

Conclusion
_{Case of Destructive Interference:}
As you see from the  simulation below_{(lower picture)} at the right  wavelength the sound wave cancels and the person
at point P_{( shown in upper picture)} will hear no sound at all( in ideal situation).
_{please look at dark} red _{and dark} blue <sub>wave shape.
Imagine that  you have two speakers one on the right  and one on the left of the  simulation below:
Imagine that  exactly in the middle of the horizontal line - the two waves destructively interfere between themselves




I'm writing  more about constructive and destructive interference in the comment  below.

Please read my comment from above.
To better understand constructive and destructive interference  here is easy explanation:

Constructive interference happens when two waves overlap in such a way that they combine to create a larger wave.
Destructive interference happens when two waves overlap in such a way that they cancel each other out.
Wave interference also depends on the relative phase of the two waves, as this video shows through the examples of path length differences and pi shifts.

The superposition of the two waves results in constructive interference, which means that the sound heard is loud.
If, on the other hand, destructive interference results in silence.

Oh, stevie/Weslie, you are at it again, following your agenda of hedging someone's interests in energy. Offering a prize for OU proof yet not accepting any proof outside science which denies OU, making fools of everyone in the process.


I'm not talking about "midpoint" interference of soundwaves, that's totally not interesting and is only an acoustical mode, non-destructive to electrons. I'm talking about EMF interference caused at VOICE COILs. That's much more interesting.


As for soundwaves vs electromagnetic waves, they are of course different. But I'm offering a way to look at other OU devices as well, using the reasoning proposed by me. EM waves also carry potential energy and thus can be used to cause a similar interference at some "interaction point". EM waves at their base are orthogonal to electricity, and to cause interference you'll have to use an "open ends" antenna or inductor. But the source of OU will be the same - opposing EMFs. OU systems with motor-alternator (like Liberty Engine 2) can be also described in the terms of opposing EMFs, but it's trickier to do. Acoustical waves are the best way to demonstrate what kind of process physics is lacking understanding of.
