A Comparison of Various Multichannel Loudness Measurement Techniques

In this study, two recently proposed objective measures of perceived loudness for monophonic audio signals are extended in several ways to deal with multichannel audio. The extensions range in complexity from a simple sum of the individual channels to the use of measured HRTFs to simulate the audio signals arriving at the ears. A database of subjective loudness matching data of multichannel audio is generated, and the performance of the various objective measures, including the particular multichannel measure recently adopted by the ITU-R, is compared against this data.
