Octave Band Filters A sound level meter fitted with Octave Band Filters has the ability to split the audible spectrum into smaller bands, identifying the frequency content of the noise. To help explain why Octave Band Filters are sometimes used, first have a look at a simple noise measurement....

This spectrum can be compared to the sound pressure levels due to other sources. For dealing with sound problems in the field, a precision sound level meter with an octave-band filter set is used; the results are reproduced in sound pressure level/frequency diagrams. It is concluded that the...
octave-band level. It is assumed that the spectrum shape does not change with level for this source. It is useful to prepare normalized spectra for standard sources, which, when added to the overall A-weightedsound level, will yield an unweighted octave-band level having the same overall ...

The center frequency definition differs depending on whetherbis odd, such as for bandwidths of 1 octave or 1/3 octave, or even, such as for bandwidths of 1/2 octave or 1/6 octave. This ensures that the band edges of the whole octave band remain band edges for all of the fractional ...
