Convention Paper

Loudness Calculation for Individual Acoustical Objects Within Complex Temporally Variable Sounds

Authors: Bradter, Cornelius; Hobohm, Klaus

AES Convention 124 · Paper 7494 · May 2008

Abstract

Models used for loudness calculation normally treat their input signal as an integral whole. For sounds consisting of two or more distinguishable acoustical objects, this contradicts listening experience. Auditory perception analyzes and identifies acoustical objects and may treat them differently. By expanding principles used in excitation synthesis based loudness models, we developed a procedure to calculate loudness of a time-varying acoustical object while a second object is simultaneously present. When signals of both objects are available individually and in combination, the procedure reflects effects of one object on the other as well as changes of loudness perception due to signal properties of one or both objects.
