Most of music occurs within two octaves in the frequency range of 220 to 880 Hz Components of an orchestra (brass, winds, and strings) produce sounds within this range The range of vocal perception a bit larger in the 30 to 5000 Hz

Octave Bands: The audio spectrum from ~ 20 Hz to ~ 20 KHz can be divided up into ~ 11 octave bands. If we set/define the 7th octave band's center frequency
But in many cases the key features of the plot can be quickly sketched by hand using some simple rules that identify the impact of the poles and zeroes in

How many octaves in a frequency range?
The human hearing range is generally taken as being 20 Hertz to 20kHz, and so musicians might wonder: How many octaves is that? The answer: 10.How do you calculate the number of octaves between two frequencies?
Given two frequencies, such as upper and lower limits for a band of noise, you can find the number of octaves between them by first finding their ratio, then taking the log of it, then dividing that by the log of 2.What octave band is 250 Hz?
How to Calculate Octaves from Frequency?
1First, determine the upper frequency (hz).2Next, determine the lower frequency (hz).3Next, gather the formula from above = #O = log (Fu/Fl) / log (2).4Finally, calculate the Octaves from Frequency.
