PROBLEM TO BE SOLVED: To obtain a head-related transfer function which reproduces the characteristics of the head-related transfer function of the listener himself / herself without actually measuring the head-related transfer function of the listener himself / herself. SOLUTION: A head-related transfer function generation device has an actually measured head impulse response acquisition unit that acquires data indicating an actually measured head impulse response of a sound wave that has reached the entrance of the external auditory canal of a listening listener, and the actually measured head impulse response. The initial head-related transfer function generator that calculates the initial head-related impulse response by multiplying by the window function and Fourier-transforms the initial head-related transfer response to generate data indicating the initial head-related transfer function, and the initial head-related transfer function. A frequency band division that divides the transfer function into a plurality of frequency bands, a process of extracting a peak or notch based on the curvature of the initial head-related transfer function for each of the plurality of frequency bands, and a process of determining a relative amplitude are executed. It also comprises a modeled head-related transfer function generator that generates data indicating the modeled head-related transfer function of the learning listener by interpolating between the points indicating the relative amplitude.
