17Hz Difference is a Heartbeat? Unlisted Video

Work in progress.

I was playing around with frequencies and binaural tones and found something rather significant. If you set two tones 17Hz from one another you create a mid-tone frequency that jumps around if passed through a tuner.

This creates a pulse, or a pattern that is quite significant. When I saw it, I immediately recognized it as a heartbeat pulse. Sure enough, if I lay over a heartbeat from a sleep-aide video it is almost identical to the visual created by the tuner, if only off on BPM.
