The perceived loudness of an audio signal is measured by modifying a spectral representation of an audio signal as a function of a reference spectral shape so that the spectral representation of the audio signal conforms more closely to the reference spectral shape, and determining the perceived loudness of the modified spectral representation of the audio signal.

Le niveau sonore perçu d'un signal audio est mesuré en modifiant une représentation spectrale d'un signal audio en fonction d'une forme spectrale de référence de sorte que la représentation spectrale du signal audio se conforme plus étroitement à la forme spectrale de référence, et en déterminant le niveau sonore perçu de la représentation spectrale modifiée du signal audio.
