On the influence of interaural correlation on binaural loudness for broadband noise

The influence of the interaural crosscorrelation factor of broad band noise on the binaural loudness is investigated for pink noise and broad band filtered white noise. An adaptive staircase method is used to compare the loudness of eleven different dichotic signals with the loudness of a diotic reference. The sound pressure level and the spectral shape of right and left ear signals are identical for ail signals compared. No influence of the interaural crosscorrelation factor on the loudness can be found despite of the different spaceousness of the sound images produced by different correlation coefficients.
