Abstract: A sound field control device has an input part through which an audio signal is input. A storage part stores a first factor obtained by calculating a proportion of energy of direct sound in total energy of sound collected in an adjustment environment within a predetermined time. A sound field generation part generates a sound field effect sound from the audio signal input through the input part, and outputs the sound field effect sound at a volume corresponding to the first factor. A calculation part calculates a second factor which represents a ratio of an energy of a direct sound to an energy of sound which is collected in a reproduction environment and which contains the direct sound. A correction part corrects the volume of the sound field effect sound based on a ratio between the first factor and the second factor.
