Uncomfortableness threshold value estimation system and method, and a program thereof; hearing aid adjustment system; and uncomfortableness threshold value processing circuit

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.

1. An uncomfortableness threshold value estimation system comprising:
one or more memories; and circuitry which in operation is configured to: present to a user a first sound, and to present to the user 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; measure an electroencephalogram signal of the user; extract, from an electroencephalogram signal which is measured within a second predetermined time from a point of presenting the second sound, and which is evoked by the second sound, a characteristic amount of an event-related potential of the electroencephalogram signal; and 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 event-related potential, the uncomfortableness threshold values not being originated with event-related potential values.
