Subjective or Psophometric Audio Noise Measurement: A Review of Standards

Authors: Wilms, Herman A.

Journal of the Audio Engineering Society · Volume 18 · Issue 6 · pp. 651–656 · December 1970

Abstract

Dynamic ranges (in dB) are meaningless if the noise measurement method is not specified. A survey is given of the CCITT, DIN, IEC, and the new CCIR standards on the psophometric measurement of audio noise. Differences in the dynamic properties and the weighting filters are discussed. Measurement of an audio noise with different weighting filters gives different values; these results are computed for a white-noise (constant density) spectrum and a red-noise (density -6 dB per octave) spectrum.
