摘要
An exemplary uncomfortable sound pressure determination system including: a sound data generator configured to generate sound data concerning sounds consecutively ascending or descending in sound pressure from first to nth sounds, the sounds being pure tones of a same frequency; an output section configured to present the sounds to a user; a characteristic amount extractor configured to extract, based on an event-related potential of the electroencephalogram signal measured after lapse of a predetermined time from a point in time of presenting each of the sounds, a characteristic amount concerning temporal change in frequency of the event-related potential; and an uncomfortable sound pressure determination section configured to determine, by referring to a previously-provided relationship by which temporal changes in frequency of event-related potentials and uncomfortable sound pressures are associated, a sound pressure corresponding to the extracted characteristic amount to be an uncomfortable sound pressure at the frequency.
