Abstract:
1. A mobile electronic device comprising: a sound emitting unit for emitting a sound based on a sound signal; a sound generation unit for generating a presentation sound to be emitted by the sound emitting unit; an input unit for receiving input of a response with respect to the presentation sound emitted by the sound emitting unit; a timer for measuring time; a determining unit for determining a value with respect to correctness of the response; a parameter setting unit for setting a compensation parameter for compensating the sound signal based on the value determined by the determining unit; and a compensation unit for compensating the sound signal based on the compensation parameter and supplying the compensated sound signal to the sound emitting unit, wherein the determining unit is configured to detect a response time from emission of the presentation sound to input of the response measured by the timer and to weight the value based on the response time.
