A sound reproduction method includes: obtaining spatial information for reproducing a virtual space which includes a structure and a sound source; identifying a listening position in the virtual space; generating one or more virtual sound sources for reproducing diffraction of sound emitted from the sound source, the one or more virtual sound sources being disposed in a neighborhood of one or more virtual sound source directions; and determining the one or more virtual sound sources based on a length of a propagation path of the sound from the sound source to a listener, the propagation path bypassing the structure. The determining includes determining at least one of (i) a sound pressure level of sound from the one or more virtual sound source directions, (ii) a total number of the one or more virtual sound sources, or (iii) a frequency characteristic of sound from the one or more virtual sound sources.
