Most measurements or evaluations of sound intensity or level are made with an electronic instrument that measures the sound pressure. The instrument ... can measure the overall sound pressure level throughout a frequency range of about 20 to 20,000 Hz, or within narrow frequency bands (such as an octave, third-octave, or even narrower ranges).  1, record 1, English, - third%2Doctave
