摘要：
An exemplary UCL estimation system including: an output section configured to present to a user a first sound, and a second sound after lapse of a first predetermined time from a point of presenting the first sound, the first sound having a sound pressure within a predetermined sound pressure range, and the second sound having a same sound pressure as that of the first sound a measurement section configured to measure an electroencephalogram signal of the user an extraction section configured to extract, from an electroencephalogram signal measured within a second predetermined time from a point of presenting the second sound, a characteristic amount of an event-related potential of the signal and an estimation section configured to estimate, by referring to a predetermined relationship between characteristic amount values of event-related potential and uncomfortableness threshold values, an uncomfortableness threshold value corresponding to the extracted characteristic amount of the potential.
