Possibly the worst assumption in audio electronics

I am NOT referring to you, BUT to your critics.

I just clarified my position, so my critics have better understanding what to criticize. 😉

By the way, experiments in quantum physics demonstrate that the Reality escapes observation. As soon as we are ready to observe it changes it's intention. May be that's why experiments that prove repeatable failure to get data freely available in different conditions are considered as if they disprove what they have to prove? 😉

Take as an example listening tests.

Yep, I read this a long time ago. Fascinating. Electrons showing some human character at last. In my case, as soon I realize the fact that I'm being observed my behaviour changes, like when I used to masturbate myself in public parks.

Just kidding, never done that.

 

[Wavebourn]

But may be humans inherit character from electrons? 😉

 

[Cassiel]

Of course.

Thatwould be neat! How do you get the sound wave to be contained in a single point vector and not spread out as a sphere?

My old concrete horn speakers were extremely directional, no spheres involved whatsoever. I read somewhere that horns can propagate parallel sound waves, whether that's true or not I've no idea but I reckon it's closer to that than a spherical wave.

I've seen concrete horns mentioned in an old article (1950's or 60's) before. Do you have any references about concrete horns?

 

[jacco vermeulen]

How big a reference ?

La Nouvelle Revue du Son, home report on someone's set-up in Japan.
Walter Burkhard (diyA member) also built a house around them.

And then there is the word concrète in French : La grande castine Fr

Just kidding

I better not ask if you had someone else do that for/to you.

 

[Cassiel]

Nothing wrong with asking but trouble may come if I answer.

Just kidding again.

My concrete horn looks like a big went grill (not really so big, about 1.5 x 3 feet) in the floor in my living room. 😀

I'll leave the chalk calculation as an exercise for the reader. It is similarly garbage.

If you ever sat in an anechoic chamber you would know that there is no such thing as silence.

 

[scott wurcer]

Wavebourn, they are NOT going to 'believe' that, either. '-)

Watch out John, you will have no choice soon but to defend Einstein as being totally correct.

There is an excellent interview somewhere with the researcher, the "teleportation" part is not quite the case.

 

[Wavebourn]

Teleportation of information may be used to reconstruct the same thingy from the same vacuum. If to assume that information teleportation happens in no time, which sound of which chalk would you hear, I mean through which channel? 😉

Probably a late 1950's Audio magazine. I remember a stacked set of JBL like concrete horns pictured on the builder's patio.

I've seen a patent on what looked like a concrete horn. I might be able to find the number if I looked for it.

My under-ground horn has "Wavebourn" molded on it. However, it is invisible through the floor, but in case of some dispute the floor can be cracked open. 😀
