WAVE TRANSMISSION CONTROL DEVICE, UNDERWATER ORGANISM GUIDANCE DEVICE, AND WAVE TRANSMISSION CONTROL METHOD

A wave transmission control device (2) to control a transmitter (300) to form a sound field in water, the wave transmission control device including a determination unit (20) to, when detection information is input from a sensor to detect an organism in water, determine a characteristic of the organism and a distribution state for every characteristic using the detection information, a sound selection unit (30) to acquire sound information based on the characteristic determined by the determination unit (20) by referring to a database (200) in which a characteristic of an organism and sound information are associated with each other, and a wave-transmission control unit (50) to determine a sound output condition in such a manner that a distribution state changes from the distribution state which is set for the characteristic received before processing starts and to cause the transmitter (300) to output a sound based on sound information acquired by the sound selection unit (30) using the output condition.
