Let's look at the biophysics of 14.2 Hz from a medical and psychoacoustic perspective.

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).

Turn off your subwoofers and listen on a cheap transistor radio. The emotional pull changes completely.

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).
