Abstract

The possibility of integrating hearing-aid technology like dynamic compression in current and future consumer audio devices raises the question how parameters of hearing supportive algorithms can be adjusted by the user to either compensate the individual hearing loss or to accommodate listening preferences. Here, three methods for measuring the auditory capacity based on loudness judgments and comparisons were evaluated. All methods used a simple interface and appear generally suited for integration in consumer audio electronics. Results of the suggested methods were compared to adaptive categorical loudness scaling [ACALOS, Brand and Hohmann, J. Acoust. Soc. Am. 112, 1597-1604 (2002)]. Gain prescriptions were derived for narrow-band loudness compensation based on the suggested methods, the clinically applicable ACALOS, and for NAL-NL2 [Keidser and Dillon, Hearing Care for Adults, 133-142 (2006)]. All loudness based procedures led to similar gains.
