This study investigates whether loudness summation can be held responsible for this finding. Two aspects of loudness summation should be taken into account: spectral loudness summation for broadband signals and binaural loudness summation for signals that are presented binaurally. In this study different aspects were investigated: (1) the effect of different symmetrical hearing losses according to the classification of Bisgaard <em>et al.</em> (2010): N2, N3, N4, S2, and S3, and (2) the effect of spectral shape of broadband signals, by using high frequency noise and low frequency noise. For the measurements we used a well-standardized technique “Adaptive Categorical Loudness Scaling” (ACALOS). Also loudness matching was applied as a potentially clinical technique to get information about the individual loudness perception. Results show large individual differences in binaural loudness perception especially for broadband stimuli.</p>}, journal={Proceedings of the International Symposium on Auditory and Audiological Research}, author={van Beurden, Maarten and Boymans, Monique and van Geleuken, Mirjam and Oetting, Dirk and Dreschler, Wouter A.}, year={2017}, month={Dec.}, pages={183–190} }
