摘要

An uncomfortable loudness level estimation system comprises: an HTL input unit (10) which receives information of a hearing threshold level in each of a plurality of frequencies; a UCL measurement point determination unit (30) which determines at least two measurement points for measuring an uncomfortable loudness level, whereby each of the at least two measurement points specifies, among a plurality of acquired hearing threshold levels, at least a first frequency relating to a first hearing threshold level and a second frequency relating to a second hearing threshold level which differs from the first hearing threshold level; a UCL measurement unit (11) which measures the uncomfortable loudness level in the at least two measurement points; a computation unit (31) which, using the hearing threshold level and the uncomfortable loudness level relating to each of the at least two measurement points which are determined by the UCL measurement point determination unit, computes a prescribed reference relating to a hearing characteristic; and a UCL estimation unit (33) which queries the prescribed reference, and estimates the uncomfortable loudness level in the frequencies corresponding to each acquired hearing threshold level.
