This part of ISO 532 specifies a method for estimating the loudness and loudness level of stationary sounds as perceived by otologically normal adult listeners under specific listening conditions. The document 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 and starts by converting a specified signal spectrum into a series of sinusoidal components representing that spectrum. This series is then transformed into a specific loudness pattern by applying four consecutive transformations, each of which is directly related to physiological and psychological characteristics of the human hearing system. Loudness is calculated from the specific loudness pattern. This method can be applied to tones, broadband noises, and to complex sounds with sharp line spectral components, e.g., transformer hum or fan noise.
