The previous papers [e.g., J. Hebrank and D. Wright, J. Acoust. Soc. Am. 56, 935–938 (1974); F. L. Wightman and D. C. Kistler, J. Acoust. Soc. Am. 101, 1050–1063 (1997)] indicated that the median plane localization mechanism requires a priori knowledge of the source spectrum. Listeners, however, localize a sound image accurately for various sound sources on the median plane, such as music, voice, and noise. Since these sources differ from each other in spectrum, it is inferred that listeners have acquired the knowledge of the source spectrum for each sound source. This paper clarifies whether a priori knowledge of the sound source spectrum is classified by the kinds of source or not in the median plane localization mechanism.
