What's up with noise reduction in the Megahertz range and why does it matter? And more about how overtones affect your listening..

"So what happens when two frequencies in the megahertz range are within beating distance? They behave in exactly the same manner as two strings. The periodicity of the beating generates a fundamental that occurs within hearing range.  Noise is a cloud of frequencies. As a result there are myriad frequencies interacting, generating a myriad of audible fundamentals." 

Joe Cohen of the Lotus Group presents his explanation of how overtones / harmonics affects a manufacturer's design decisions.

Joe does a wonderful job of explaining how to hear overtones, offers a simple explanation of the overtones of a string and how to extract these sounds from a string.  Enjoy!
