PROBLEM TO BE SOLVED: To provide a hearing test device allowing easy calibration without requiring a professional adjusting person. SOLUTION: This hearing test device testing the hearing of a subject has a sound output means outputting test sound for hearing test to the outside; a sound input means taking in the test sound outputted to the outside; a detection means detecting an input signal level of the taken-in test sound; and a storage means storing a reference value of the test sound to a prescribed frequency; a start signal input means inputting a signal starting the calibration of the test sound outputted from the sound output means; and a calibration means making the test sound output from the sound output means on the basis of the reference signal value stored in the storage means when the start signal is inputted, and calibrating the output of the test sound such that the input signal level detected by the detection means has prescribed relation to the reference value.
