Actually some of the guys who measure absorption in echoic chambers have been finding that the traditional formulas may be wrong. It may actually be that it is the absorption at the boundaries that does most of the work!

The mic - delay - loudspeaker system for concert hall or similar use is offered by two major manufacturers.

Immediately after I installed such a system the reviewers who were not aware of any such change were quite surprised by the difference, but attributed it to a different cause. Management kept very quiet about their new secret!

SY you understand we disagree on this issue of intent. I think the folks who offer these unusual products and the folks who review them are sincere. So I give them the benefit of the doubt.

So I think the real issue is that I prefer not to make fun of what appear to be unsupported claims, you don't. But if you send me your credit card number ....

I admittedly have a low tolerance for fraud.

Should we give back New York city? The guys who took the beads weren't even of the right tribe?

(Would they want it back?)

So our disagreement is I think the reviewers certainly are sincere and most of the "Manufacturers."

I suggest we do the honorable thing and duel it out. Water pistols tomorrow at high noon. I'll shoot in your direction you in mine. First to soak the other guy wins!

If these folks actually have anything that is serious, they should say so, or they will be ridiculed to no end. So will the reviewers. Who knows, snake oil may actually be good for something other than lubricating snakes. If so, explain it. "Make oxygen more conductive to sound". Yea, it is called LOX. As a liquid, it will transfer vibration more efficiently. I doubt they are making your room -267 C.

A salesman was demonstrating the "clear difference" between a generic decent cable and whatever he was making his boat payment off that month. Yup, a clear difference. His special cable rolled off at about 12K. I never returned. They are gone.

This phenomenon is similar to static and dynamic friction. To force a heavy piece of rock to move is not an easy task. But if it is once moving it can be much easier shifted further. The Steinmusic Harmonizer is working very similar, but rather at a level of ethereal states...."

OK, now you can laugh. There's nothing so stupid that you can't find someone gullible enough to believe it.
It is actually kind of funny description of an air heater.

Only if your room is at absolute zero, otherwise the oxygen molecules are already zipping around quite rapidly. I wonder why this isn't claimed to affect the nitrogen molecules, after all, they're 80% of the air in the room.

We never covered "ethereal states" in my physics degree. I think I will have to complain; I thought I was receiving a good education but obviously something important was missing. I can't complain about not hearing of air stiction before, as I skipped the module on fluid dynamics.

When I saw the device was called H2 I assumed it was pumping out oxygen-free Dihydrogen Monoxide - that would certainly mean your music listening would go with a bang. Very high quality snubbers would be needed on all switches in order to maintain the structural integrity of your house.

You, as a chemist, ought to know that H2 "stimulates" oxygen molecules much better than it does nitrogen.

Of course, how silly of me. That's why it's good to have physicists around.
