Dude, you may be onto something. I had a friend in high school who knew all the tones on a keypad. You could type a number on the phone and she would know what number it was from the other end of the phone. I wonder if each of these soundwaves could be individually propagated and compared to what is actually happening in the blockchain at the time. Then the sound could be correlated to the specific task happening. Thanks for sharing @granturismo89
