Abstract

Subjects with similar hearing thresholds showed large differences in loudness summation of binaural broadband signals after narrowband loudness compensation. Based on these findings, the fitting method trueLOUDNESS was developed to restore the individual binaural broadband loudness perception. In the present study, the trueLOUDNESS fitting method was compared with NAL-NL2. Loudness judgements of different vehicles’ sounds were compared with average judgements by normal-hearing subjects. The loudness judgements with trueLOUDNESS fittings were closer to normal compared to the loudness judgements with NAL-NL2 fittings. This study shows that the lab measurement of binaural broadband loudness perception has validity beyond the laboratory.
