[QUOTE="sailor, post: 1116505, member: 1530"] @Sarel, you are missing the point! I don't understand why you would mention transduction and rectification which has nothing to do with this topic. Have you ever tried a supertweeter that goes out to 60K and beyond? Neither I nor the info in the link I provided claim that it's possible to hear an isolated sound above 20K. What is being claimed is that the very high frequencies help complete the waveform. The higher-order harmonics by themselves are inaudible but are necessary if you want a complete waveform faithful to the waveform produced by the instrument. Any sound produced is comprised of it's fundamental which is a pure sine wave and it's associated harmonics and these harmonics are what allow you to hear if the instrument note is from a guitar or a trumpet or cymbal. Without a harmonic structure all instruments would sound the same. If that makes sense to you then surely you can grasp the fact that frequencies above 20K are part of the musical signal though on their own are not audible to the human ear. [/QUOTE]
