theta wave (10. 994)

Coincidentally on the anniversary of the mega-structure’s inauguration on this day in 1936 when Franklin D Roosevelt pressed a button in Washington, DC to start the first hydroelectric generator for a test-run on the Nevada-Arizona border (the dedication ceremony came at the month’s end), Weird Universe reports on the therapeutic potential of the acoustics properties of Hoover Dam. Whilst the soothing effects maybe somewhat exaggerated and over-simplified, binaural beat (as they are contemporaneously and unfortunately we could not find an audio sample either), the resolution of the auditory illusion that takes place in the brain when one hears two slightly different tones in stereo (as from an echo) is the frequency-follow response. Indulging and synchronising this discrepancy can in some instances induce a mental state of relaxation though a fair number of listeners report a short-lived burst of anxiety and anger and generally finding the experience unproductive.
