How we hear.

@tony1954 Looks like this thread is just not taking off. Suprising, but anyway I'm interested in your thoughts on the video.

Tony, there is a lot there but let’s start with the graphs of fundamental tones from an organ and how they change into different "instruments" as the pattern of harmonics change. That looked a lot like measures of harmonic distortion from amps and other devices. It explains why harmonic distortion, say from tubes, is not always a bad thing, our hearing is just receiving a different timbre. Also that "diistorion" per se is not a unique product of hifi systems, it is really inherent in all music. We are very accustomed to low order harmonic distortion because it is "natural". Good stuff, thanks!
