Managing the Equalizer

This procedure shows how to set the general parameters of the equalizer.

With an equalizer you can vary the sound intensity from -75 dB to 25 dB in each frequency band (Hz) of the equalizer. The 3 equalizers available in Sound: Analysis and Specification are the Octave band, the Third octave band and the Bark band equalizers.

  • The Octave and Third octave equalizers follow standardized frequency band. The Octave band equalizer has ten frequency bands (also known as the Octave bands). One octave separates the lower and the upper frequencies of each frequency band. In Sound: Analysis and Specification, the central frequency is displayed at the bottom of each frequency band. For example, 31.8 Hz is the central frequency of the first frequency band.
  • The Third octave band equalizer is similar to the Octave band equalizer, except that the Third octave band equalizer has 31 frequency bands. 1/3 octave separates the lower and the upper frequencies of each frequency band. In Sound: Analysis and Specification, the central frequency is displayed at the bottom of each frequency band. For example, 20 Hz is the central frequency of the first frequency band.
  • The Bark band equalizer has 25 frequency bands (also known as the Bark bands). Bark bands are related to human hearing. Bark bands are also known as Critical Bands. See also Bark scale and Critical Bands.
