Comment: Primal hum of the electrical grid (Score 2, Interesting) 525

Interesting side effect of the difference in AC power frequencies between US (60 Hz) and Europe (50 Hz). I recall reading about a study that asked groups of participants to mediate and then collectively hum a tone of "primal unity"

The USian group centred on a B-flat (multiple of 60 Hz), while the Europeans centred on an A-natural (multiple of 50 Hz).

Hardly qualifies as a controlled study. But still suggestive that the background EMF frequency and device hum has some unconcious influence on the psyche?

The best book on programming for the layman is "Alice in Wonderland"; but that's because it's the best book on anything for the layman.

Working...
