Abstract: A sound pressure assessment system determines sounds to be presented by referring to a database retaining data of sounds, each of which is a pure tone. The system presents the determined sound as a first sound, and in a predetermined time after presenting the first sound, presents as a second sound a sound at least having the same frequency and the same sound pressure level as those of the first sound to the user. The system extracts an amount of change from an N1 component in response to the first sound to that in response to the second sound. The N1 components are negative components of an user's event-related potential based on points of presenting the first and second sounds as respective starting points. The system determines whether the sound pressure level of the presented sound is excessive to the user, based on the amount of change.
