W22 - CURRENT ISSUES IN BINAURAL LOUDNESS ASSESSMENT

Chair:
Ville P. Sivonen, University Hospital of Oulu - Oulun Yliopisto, Finland
Panelists:
Pavel Zahorik, University of Louisville - Louisville, KY, USA

Abstract:
The most commonly-used standardized model for predicting the loudness of sound fields (ISO-532B, 1975) relies on the use of monophonic acoustical measurements and does not take into account the signals that actually reach a listener’s ears. That is, the acoustical input to the model is obtained in the absence of a listener, using a microphone placed in the position where the center of the listener’s head would be. Binaural sound fields encountered in typical measurements are more complex than those assumed by the standard model, most often consisting of a combination of spatially localized sound source(s) and spatially distributed indirect sound. Workshop panelists will discuss current issues in binaural loudness modeling and report the results of recent studies on directional loudness perception.
