We now continue our discussion of the 10 audible octaves. We left off at Octave 5 in Part 1. Onward….

Characteristic Sounds: Bands 6-10

Octave 6 (640-1280Hz)

This is midrange land again. Remember Octave 5, and now 6 are referred to as the projection octaves.

Specifically, here in Octave 6 rests the difference between Click to read the rest…

Now comes the time that we need to address actual characteristics of different frequencies, as well as the different octaves that humans can hear. (As in, how many are there actually?)

As always, let’s follow the flow of logic. The simple question first:

How many octaves are there in the human hearing range of 20-20kHz?

The answer is 10.

If we take the lowest frequency humans can hear, which by now you know is 20Hz, and then simply double that number until we reach the 20k range, we’ll end up with 10 total octaves encompassing the 20-20kHz range.

Here is the exact break down: Click to read the rest…
