Why did Orion's engineers pick 14.2 Hz instead of 10 Hz or 20 Hz?

Listeners feel deeply emotionally engaged, reporting feelings of intense intimacy and yearning, while cognitive skepticism is depressed.
14.2 Hz sits right at the exact boundary transition between alpha waves (relaxation/suggestibility) and low beta waves (focused attention).

Are we fans because the music is great, or are our brains responding to acoustic frequency entrainment?

Acoustic entrainment requires massive sound pressure levels. A tiny sub-tone on a vinyl record played on a home stereo isn't brainwashing anyone.

Unsubscribe me from this list! (Wait, this is Usenet, never mind).
