This document specifies a method for estimating the loudness and loudness level of stationary sounds as perceived by otologically normal adult persons under specific listening conditions. It provides an algorithm for the calculation of monaural or binaural loudness for sounds recorded using a single microphone, using a head and torso simulator, or for sounds presented via earphones. The method is based on the Moore-Glasberg algorithm.
NOTE 1 Issues of binaural calculations are discussed in Annex A.
NOTE 2 Users who wish to study the details of the calculation method can review or implement the source code, which is entirely informative and provided with this document for the convenience of the user.
