The setting unit sets a sound stimulus of a sound volume level of 65 decibels or more and a frequency of a value from 5 to 250 hertz. The sound generator may generate a sound stimulus of a continuous sound or generate a sound stimulus in an intermittent pattern in which an output period of the sound stimulus and a non-output period of the sound stimulus are alternately repeated. The setting unit may determine the sound volume level generated from the sound generator according to the distance to a subject.
