How do you calculate 1 3 octave band frequencies?
A band is said to be an octave in width when the upper band frequency is twice the lower band frequency. A one-third octave band is defined as a frequency band whose upper band-edge frequency (f2) is the lower band frequency (f1) times the cube root of two.
What is a 1/3 octave EQ?
OK, so now we know what an octave is and what the 10 octaves of human hearing range are. What is 1/3 octave? We… it is simply the same 20Hz – 20kHz range broken into 1/3 octave slices. Calculating 1/3 octave intervals is pretty easy too. You simply start at 20Hz and multiply it by 1.26 to get 25.2Hz.
Why do we use 1/3 octave band?
Mainly used in environmental and noise control applications, 1/3 Octave Bands provide a further in-depth outlook on noise levels across the frequency composition. Each 1/1 (single) Octave is further split into three, providing a more detailed view of noise content.
