Abstract: An exemplary uncomfortable sound pressure evaluation system consecutively presents sound stimulation groups to a user. Each sound stimulation group includes a sound stimulation, and the sound stimulation groups differ in frequency from one another. The system includes: an extraction section configured to extract, for each sound stimulation group, information concerning event-related potential relating to the sound stimulation; an estimation section configured to estimate an uncomfortable sound pressure (UCL) of the user from the information concerning event-related potential; and a correction section configured to determine whether the estimated UCL is higher than a predefined maximum UCL or not, and if a proportion of those determination results which indicate the UCL to be higher than the maximum UCL is smaller than predetermined, correcting each UCL determined as higher than the maximum UCL to a sound pressure equal to or less than the maximum UCL.
