What's the deal with the Machina Dynamica Clock?


Just my uninformed and untested opinion, and maybe I am wrong, but this Clever Little Clock sounds more like a Clever Little CROCK to me. Any true believers are welcome to enlighten me, but don't expect me to whip out the credit card just yet. Don't mean to "tick" anyone off. Note: sarcastic skeptical scoffers are also very welcome to post to this thread. :)

The scientific journals may not beat a path to your door, Rcprince, but I'd say this was a reasonable stab at trying to learn something. By my count, your subjects got 45 correct (16+5+19+5) and 43 incorrect (6+17+3+17). That's pretty much 50-50, which means it looks like your subjects were just guessing and couldn't really hear any difference.

The fact that one guy scored perfectly means nothing by itself; with 22 subjects, somebody's bound to go 4 for 4 on luck alone. Had you more time, and wanted to be more scientific, you could have repeated the test with that individual, and made it double-blind. My money says he'd have "regressed to the mean," as they say.

Important caveat: One test cannot prove that this clock makes no difference. But quibbling over the weaknesses of this test doesn't prove anything, either. If anyone cares to defend this silly clock, they need to do a better test.

Prediction: The Machina Dynamica Web site will soon brag that, in a careful study, members of the New Jersey Audio Society correctly identified whether the clock was in the room or not more than half the time.

Second prediction: Some people will believe this.
Could you explain how this product works and what is to be expected?

If he told you, would you believe him??
I have no experience with the product but I believe Geoff has a right to make a living so let him sell his products to whoever wants to buy them.
