Acoustic holography is to predict sound field by sound pressure values on measurement plane while sound field reproduction is to generate sound field by loudspeakers. They have absolutely different objectives but handle sound field so that they have a common mathematical approach according to the shape of the sound field of interest. Hence several methods of sound field reproduction, WFS, ambisonics, BPC, mode matching method, etc., correspond with each category of acoustic holography: plane holography, cylindrical holography and spherical holography, etc. In this paper, mathematical and technical similarities are introduced and discussed.
