Octave-band analyzers or Real-time analyzers are particular sound level meters that separate noise into its components of frequency. Electronic filter circuits are utilized to separate the noise or sound into its own frequency bands. Most octave-band filter sets give filters the listed center frequencies: 31.5, 63, 125, 250, 500, 1,000, 2,000, 4,000, 8,000, and 16,000 Hertz (Hz). For an in-depth analysis, sometimes, the spectrum is measured in one-third octave bands.
Real-time analyzers or octave-band analyzers are used to:
Assist in determining the adequacy of different types of frequency-dependent noise controls; Select hearing protectors since they can make measurements of the attenuation amount (how much a sound is weakened) provided by the protectors in select octave bands; Analyze the frequency content of noise.
