Frequency Charts



Hey folks

Just curious as to the reason they graph out frequency charts as they do. What im refferring to is the fact that they Display 20 - 100hz on the first 1/4 of the chart, then 100hz to 1khz on the 2nd quarter, followed byu the 1k-10k, and lastly the 10-20k, meaning they graph out half of the hearing range in the last 1/4

i guess this is a kind of a dumb question, it just seems that by reading the first half of the graph covers just 1/20th of the range while the other 19/20th's are all crammed together.

i know that it would be pretty difficult to put a graph in a magazine of 20,000 without using some technique to compact it. Is there any logical reason that group it out the way they do other than to save space?

Onhwy is right. It's easy if you look at the piano. Each octave doubles the frequency. Middle C is 260 Hz. One octave up is 520, the next octave is 1040. So if you were to mark all the 'C's on the piano on a log scale they would be evenly spaced.
