PROBLEM TO BE SOLVED: To provide a device that is simply installed and easily managed and operated by outputting an inspection sound signal stored in an inspection sound storage means to an external input terminal of a hearing aid. SOLUTION: An inspection sound signal selection section 2c is operated to call a calibration sound file from an inspection sound file storage section 1 and an inspection sound signal conversion section 2a obtains an analog calibration sound signal from the calibration sound file. Then a gain of a gain variable amplifier 3 of a calibrator 2b receiving the analog calibration sound signal is adjusted so that an arithmetic result by an equivalent sound pressure level arithmetic section 4 that is displayed on an equivalent sound pressure level display section 5 reaches a prescribed sound pressure at recording of a calibration sound. Moreover, an inspection sound signal selection section 2c is operated, the inspection sound file is selected from the inspection sound file storage section 1 and the inspection sound on the basis of the inspection sound file is exhibited a person wearing a hearing aid. The exhibited inspection sound is given to an amplifier section 6c of the hearing aid 6 as an output voltage of the calibrator 2b, hearing-aid-processed and the resulting inspection sound is emitted.
